Problem: Background: Feeder are a Welsh rock band formed in Newport, Wales. They have released ten studio albums, twelve compilations, four EPs, and 40 singles. They have spent a total of 182 weeks on the singles and albums charts combined as of 2017, and have accumulated 25 top 75 singles between 1997 and 2012. At their peak of commercial success, Feeder won two Kerrang!
Context: After building a strong fanbase with the release of Swim, the band released their first full-length album in 1997. The result Polythene, was one of the most critically acclaimed albums of 1997 with Metal Hammer and Kerrang!, placing the album at first and sixth in their respective end of year lists. Kerrang! later included the album in their 200 Albums For the Year 2000 list in the "Essential Britrock" category. Two tracks from Swim were used for the album, being "Descend" and "Stereoworld". After the recording sessions were completed, the album's first single "Tangerine" was released and charted at #60 in the UK singles chart. This was followed by "Cement", charting at #53 and then the release of the album which charted at #65. Two more singles were released before and after their main stage debut at the Reading festival, with "Crash" making number #48, while "High" charted at number #24. The album as of May 2017, has sold 100,000 copies, certifying the album Gold twenty years after its original release. They also re-issued the album in October 1997, with "High" included and the "Stereo World" b-side "Change" replacing "Waterfall" from the original track list. Also included as an enhanced element was the video for "High". The album caused many critics to label the band "The UK's answer to the Smashing Pumpkins", and also draw comparisons to The Pixies and Talk Talk. In early 1998, following the band's final 1997 tour in support of Polythene, the band travelled to the United States as a support act for Everclear. During their U.S. tour, the band released a re-worked version of "Suffocate" for UK release, which charted at #37. After their return to the UK, they played their own headline tour with Everclear this time in the supporting position. Later that year, Feeder started to play various music festivals in the United States, alongside a headline tour with "High" being released to radio stations and charting at #24 on the Billboard Modern Rock Tracks chart; it was the follow-up to "Cement" which had charted at #31, also on the same listing. During the band's first U.S. tour, Grant broke his ankle and picked up other injuries, while finding it hard to sleep at nights. This inspired him to write "Insomnia", which later appeared on their second album. They stayed in the U.S. for the majority of the year, with a trip back to the UK for their V98 appearance. Feeder later included live-only guitarist Dean Tidey; Grant once said in an interview with Kerrang!, that he was considering bringing in another guitarist for their live gigs.

Problem: Background: Philip Chapman Lesh (born March 15, 1940) is a musician and a founding member of the Grateful Dead, with whom he played bass guitar throughout their 30-year career. After the band's disbanding in 1995, Lesh continued the tradition of Grateful Dead family music with side project Phil Lesh and Friends, which paid homage to the Dead's music by playing their originals, common covers, and the songs of the members of his band. Lesh operates a music venue called Terrapin Crossroads. He scaled back his touring regimen in 2014 but continues to perform with Phil Lesh & Friends at select venues.
Context: Lesh was an innovator in the new role that the electric bass developed during the mid-1960s. Contemporaries such as Casady, Bruce, James Jamerson and Paul McCartney adopted a more melodic, contrapuntal approach to the instrument; before this, bass players in rock had generally played a conventional timekeeping role within the beat of the song, and within (or underpinning) the song's harmonic or chord structure. While not abandoning these aspects, Lesh took his own improvised excursions during a song or instrumental. This was a characteristic aspect of the so-called San Francisco Sound in the new rock music. In many Dead jams, Lesh's bass is, in essence, as much a lead instrument as Garcia's guitar. Lesh was not a prolific composer or singer with the Grateful Dead, although some of the songs he did contribute--"New Potato Caboose", "Box of Rain", "Unbroken Chain", and "Pride of Cucamonga"--are among the best-known in the band's repertoire. Lesh's high tenor voice contributed to the Grateful Dead's three-part harmony sections in their group vocals in the early days of the band, until he largely relinquished singing high parts to Donna Godchaux (and thence Brent Mydland and Vince Welnick) in 1976 due to vocal cord damage from improper singing technique. In 1985, he resumed singing lead vocals on select songs as a baritone. Throughout the Grateful Dead's career, his interest in avant-garde music remained a crucial influence on the group. In 1994, he was inducted into The Rock and Roll Hall of Fame as a member of the Grateful Dead.
