The Automatt was a sound recording studio in San Francisco, California, promoted for its early mix automation system.
During its eight active years, 1976 to 1984, it was one of the top recording studios in the region.
The Automatt was founded by producer David Rubinson and opened in an existing studio subleased from Columbia Records, who continued to record in the same building for a few years; thus it was sometimes referred to as CBS/Automatt.
Rubinson leased the whole building in 1978 and from that point, operated three rooms for recording and mixing, a mastering room, a rehearsal room, and offices.
The studio complex was known for its top-notch equipment, for the hit records it produced, and for the famous artists who recorded there.
Under Rubinson and chief engineer Fred Catero it served as the training ground for respected recording engineers such as Leslie Ann Jones and producers such as Scott Mathews. 
William Cawthorne Unwin FRS (12 December 1838 – 17 March 1933) was a British civil and mechanical engineer.
He is noted for his extensive work on hydraulics and engines as well as his close association with William Fairbairn.
He is one of only a few men who have served as president of both the Institution of Civil Engineers and the Institution of Mechanical Engineers.
Unwin served as an engineering advisor to the government during the First World War and was the first recipient of the Kelvin Gold Medal awarded by the Institution of Civil Engineers. 
Howard's musical career began when he was seven when he began playing acoustic guitar for a folk rock group The Pathfinders, which also featured Howard's father John, who also played acoustic guitar for the group.
However, Howard really rose to prominence as a member of the Royal Engineers Acoustic Band, which he played acoustic guitar from during his later years with the Royal Engineers.
He played in the group alongside his fellow Royal Engineers from 1979 to 1985.
In 1985, he left the Royal Engineers to pursue a career as a solo recording artist, and found himself working with the likes of The Christians and Paul McCartney.
In 1986, Howard became noticed by the a cappella group The Flying Pickets, who had had a hit in the charts years before with a cover version of Yazoo's "Only You".
The Flying Pickets recruited Howard to play backing acoustics during their recording and performing sessions, and through his years with The Flying Pickets he became close friends with the band's late lead vocalist Brian Hibbard.
Howard remained with the band for over a decade, before departing to pursue a solo music and acting career, although he remained close to Hibbard right up to Hibbard's death from cancer in 2012. 
The band began recording demos of new material in 2009.
All three members brought song ideas that they worked on for years.
As the band got back together, Barker said that the trio immediately "got inspired" by practicing their old songs and listening to them again, and they decided to record demos.
There were four demos done, and only one was near completion, "Up All Night".
The trio wanted to release it as a single then, but quickly they realized that it was too ambitious to complete it before their reunion tour began in July.
Sessions were stalled by the summer 2009 reunion tour, during which the band reconnected musically and emotionally.
During the tour, Barker got the phone call that DJ AM had overdosed and died in New York, which heavily affected him.
In addition to the tragedy regarding DJ AM, DeLonge was diagnosed with skin cancer the following year, but it eventually was cleared.
The band did a large amount of writing before leaving on tour, but upon completion of the tour, they took time off to "take a couple of months and chill and do other stuff," with intentions to regroup in 2010.
In June and July 2010, the band spent time at their rehearsal spot, and their intention was to wrap up touring by September, and stay in the studio for the rest of the year until the album was finished.
The album sessions were to be partially documented in "The Blinkumentary", which was scrapped in 2012.
The recording and release of "Neighborhoods" was delayed multiple times.
The recording's delay was due to the way the band chose to work — in bits and pieces, alone and together, in a pair of California studios — in addition to each member's busy schedules.
The album was recorded at both DeLonge's studio in San Diego and in Los Angeles by Hoppus and Barker.
Recording in separate studios was DeLonge's idea, and ideas were exchanged via e-mail.
Various engineers met up in person to trade files on hard drives.
Although the three musicians were rarely in the same room while recording, opting to work on their parts individually, DeLonge asserted that the method of recording was a more efficient way of working considering the schedules, not due to a lack of unity within the band.
In addition, Barker was releasing a solo record, DeLonge was involved in Angels & Airwaves, and Hoppus had to fly to New York City once a week to film his television show, "Hoppus on Music".
The record was the band's first to be self-produced, due to the death of long-time producer Jerry Finn in 2008.
Not only did Finn helm their last three studio albums, but he served as an invaluable member of the band: part adviser, part impartial observer, he helped smooth out tensions and hone their sound.
"I honestly still feel like he’s in the studio with us, because for me, personally, everything that was about recording and being in a studio, I learned from Jerry," said Hoppus.
Instead of a producer, each band member had their own dedicated sound engineer.
DeLonge, who was against using a producer after self-producing most of his Angels & Airwaves records, described the band situation as "very democratic," noting that he learned during the recording process to "let go and be okay with not being able to control everything.
"Hoppus attributed the album's delay to the band learning to work by themselves without Finn, and both DeLonge and Hoppus expressed frustration during the sessions at the band's cabal of publicists, managers and attorneys (which DeLonge described as "the absolute diarrhea of bureaucracy").
A result of the band's split was each members hiring his own attorney, and, during the sessions of "Neighborhoods", the band had four managers.
Hoppus moved to London with his family late in the recording process, also complicating matters.
Under pressure, the band released a statement in April that effectively rescheduled all European tour dates due to the album's prolonged recording.
The decision — a "hugely expensive" one — was protested by DeLonge but pushed forward by Barker, who felt the trio had made commitments to only tour with new material.
The biggest argument of the recording process ensued, which resulted in Geffen Records setting a July 31 deadline for the record amid concerns about the volatility of the band, explaining there would be penalties if the album was not turned it on time.
DeLonge joked that, "We'll probably actually drive it to the (Geffen) president's house at two in the morning and hand it through his bedroom window at the last possible minute."
The band, as a whole, only entered the studio for "one or two weeks" following the release of the statement in the spring, with only three days dedicated to writing.
Recording lasted through May and into the summer, and by the time of the July 31 deadline, the record was near completion and finally completed over August. 
Roberts was a member of the American Society of Civil Engineers, the Structural Engineers Association of California and served one year (1972) as State President of the Professional Engineers in California Government, the bargaining unit which represents Professional engineers, land surveyors and related classes who are civil servants for the state of California.
He was an Honorary member of the American Concrete Institute among many other memberships.
In 2007, the Members of the California State Legislature passed the bill to rename the Tuolumne River Bridge as the James E. Roberts Bridge.
He received the Roebling Medal by the ESWP Engineers Society of Western Pennsylvania for Lifetime Achievement in Bridge Engineering.
