Boston is an American rock band from Boston, Massachusetts, who had their most notable successes during the 1970s and 1980s. Centered on multi-instrumentalist founder and leader Tom Scholz, the band is a staple of classic rock radio playlists. Boston's best-known works include the songs "More Than a Feeling", "Peace of Mind", "Foreplay/Long Time", "Rock and Roll Band", "Smokin'", "Don't Look Back", "A Man I'll Never Be", and "Amanda". They have sold more than 75 million records worldwide, including 31 million albums in the United States, of which 17 million were from their self-titled debut album and seven million were for their second album,

Tom Scholz first started writing music in 1969 while he was attending Massachusetts Institute of Technology (MIT), where he wrote an instrumental, titled "Foreplay". While attending MIT, Scholz joined the band Freehold, where he met guitarist Barry Goudreau and drummer Jim Masdea, who would later become members of Boston. Vocalist Brad Delp was added to the collective in 1970. After graduating with a master's degree, Scholz worked for Polaroid, where he used his salary to build a recording studio in his basement, and to finance demo tapes recorded in professional recording studios. These early demo tapes were recorded with (at various times) Delp on vocals, Goudreau on guitar, Masdea on drums, and Scholz on guitar, bass and keyboards. The demo tapes were sent to record companies, but received consistent rejections. In 1973 Scholz formed the band Mother's Milk with Delp, Goudreau, and Masdea. That group disbanded by 1974, but Scholz subsequently worked with Masdea and Delp to produce six new demos, including "More Than a Feeling", "Peace of Mind", "Rock and Roll Band", "Something About You" (then entitled "Life Isn't Easy"), "Hitch a Ride" (then entitled "San Francisco Day"), and "Don't Be Afraid". Scholz stated they finished four of the six by the end of 1974, and they finished "More Than a Feeling" and "Something About You" in 1975. Scholz played all the instruments on the demos, except for the drums, which were played by Masdea, and used self-designed pedals to create the desired guitar sound. The violin-like sound of the guitars was created in the early 1970s by Scholz. This final demo tape attracted the attention of promoters Paul Ahern and Charlie McKenzie. Masdea left the band around this time. According to Scholz, the managers insisted that Masdea had to be replaced before the band could get a recording deal. Years later, Delp told journalist Chuck Miller: "[Jim] actually told me he was losing interest in playing drums. I know Tom felt very bad when the whole thing happened. And then, of course, we started getting some interest." Scholz and Delp signed a deal with Epic Records after Masdea's departure, thanks to Ahern and McKenzie. Before the deal could be finalized, the band had to do a live audition for the record company executives. The duo recruited Goudreau on guitar, bassist Fran Sheehan and drummer Sib Hashian to create a performing unit which could replicate Scholz's richly layered recordings on stage. The showcase was a success and the band agreed to put out ten albums over the next six years. In addition to the firing of Masdea, the record label insisted that Scholz re-record the demo tapes in a professional studio. However, Scholz wanted the record to be recorded in his basement studio so that he could work at his own pace. The label agreed, and offered to split the producer's royalty with Scholz. Upon request of Scholz, Masdea played drums on the track "Rock and Roll Band", and the instrumentation was recorded in Scholz's studio. The multitrack tapes were then brought to Los Angeles, where Delp added vocals and the album was mixed by John Boylan. It was then that the band was named "Boston", by suggestion of Boylan and engineer Warren Dewey. In late 1979, Scholz began writing new material, but Boston's former co-manager, Paul Ahern, argued that, according to an agreement Scholz had signed years earlier with Ahern, Ahern owned a percentage of all songs Scholz wrote from that point on. Delayed further by the dispute, Scholz suggested that in the meantime the individual members should work on whatever other projects they might be considering. Goudreau then decided to record a solo album that featured Boston members Delp and Hashian, and which was recorded with the help of Paul Grupp, an engineer and producer familiar with Scholz's studio techniques. The album, released in 1980, was titled Barry Goudreau and featured the minor hit single "Dreams". There was tension when CBS's marketing connected Goudreau's solo album to Boston's signature guitar sound, despite Scholz not having played at all on this album. Scholz objected to the ad copy, but it became irrelevant when Epic dropped promotion on Goudreau's album citing lack of interest. Goudreau left the band in 1981 and formed Orion the Hunter. Delp contributed vocals and co-wrote songs on the debut album, but returned to Boston and recorded vocals on the third Boston album. While Scholz and Delp were recording new material for the third Boston album, CBS filed a $60 million lawsuit against Scholz, alleging breach of contract for failing to deliver a new Boston album on time. During this same period, Scholz founded his high-tech company Scholz Research & Development (SR&D), which made amplifiers and other musical electronic equipment. Its most famous product, the Rockman amplifier, was introduced in 1982. The legal trouble slowed progress toward the completion of the next album, which took six years to record and produce. Joining Scholz in the album's development again were Delp and Jim Masdea. In 1985, guitarist Gary Pihl left Sammy Hagar's touring band to work with Scholz as both a musician and an SR&D executive. As CBS v. Scholz played out in court, CBS opted to withhold royalty payments to Scholz, hoping to force him to settle on unfavorable terms. The lawsuit's first round was eventually decided in Scholz's favor, and Scholz moved the band to MCA Records. By spring 1990, Scholz was back in the studio working on the band's fourth studio album. Later that year, Delp told Scholz he wanted to concentrate on other projects, and might not be available for some time. With Delp's departure, Scholz was then the last remaining original member. Before he left, Delp co-wrote with Scholz and David Sikes the song "Walk On", which eventually became the title track of the new album. Delp subsequently joined Barry Goudreau's new band, RTZ. Scholz eventually replaced him with Fran Cosmo, who had been in Goudreau's previous band Orion the Hunter. For the second album in a row, and for the second time in a decade, Scholz's work was delayed by renovations to his studio. In the end, eight years passed between Third Stage and Walk On, which was released in June 1994. Walk On was certified platinum by the RIAA, and reached No. 7 on the Billboard Top 200 Albums chart. Unlike Boston's previous albums, it failed to chart in the top 5. It produced one hit single, "I Need Your Love", which was widely played on some rock radio stations. Delp reunited with Boston at the end of 1994. Their first appearance was for two benefit shows at the House of Blues on December 12-13, 1994, in Cambridge. The band also handed a check of $5,000 to Globe Santa and another check of $5,000 to Operation Christmas in Fall River. The group, with Delp now back in the band, toured in the summer of 1995 with both Cosmo and Delp combining vocals. By that time drummer Huffman had been replaced by Curly Smith, who was previously with Jo Jo Gunne. Following the conclusion of the "Livin' For You" tour in 1995, Scholz announced that a greatest hits album would be released. Initially planned for release in August 1996, the album was pushed back to a 1997 release date.
