Problem: Background: Bruce Randall Hornsby (born November 23, 1954) is an American singer and pianist. Hornsby draws frequently from classical, jazz, bluegrass, folk, Motown, gospel, rock, blues, and jam band musical traditions. Hornsby's recordings have been recognized on a number of occasions with industry awards, including the 1987 Grammy Award for Best New Artist with Bruce Hornsby and the Range, the 1990 Grammy Award for Best Bluegrass Album, and the 1994 Grammy Award for Best Pop Instrumental Performance. Hornsby has also achieved recognition for his solo albums and performances, his touring band Bruce Hornsby and the Noisemakers, his bluegrass project with Ricky Skaggs and his appearances as a session and guest musician.
Context: Bruce Randall Hornsby was born in Williamsburg, Virginia, a son of Robert Stanley Hornsby (1920-1998), an attorney, real-estate developer and former musician, and his wife, nee Lois Saunier. Raised a Christian Scientist, he has two siblings: Robert Saunier "Bobby" Hornsby, a realtor with Hornsby Realty and locally known musician, and Jonathan Bigelow Hornsby, an engineer who has collaborated in songwriting.  He graduated from James Blair High School in Williamsburg, Virginia, in 1973, where he played on the basketball team. He studied music at the University of Richmond, as well as Berklee College of Music and the University of Miami, from which he graduated in 1977.  In the spring of 1974 Hornsby's older brother Bobby, who attended the University of Virginia, formed the band "Bobby Hi-Test and the Octane Kids" to play fraternity parties, featuring Bruce on Fender Rhodes and vocals. The band, which is listed in Skeleton Key: A Dictionary for Deadheads, performed covers of Allman Brothers Band, The Band, and predominantly Grateful Dead songs. Although Hornsby's collaboration with Bobby Hornsby would be relatively short-lived, Bobby's son R.S. was a recurring guest-guitarist with Hornsby's band and periodically toured with his uncle. His performances were often looked forward to by fans. R.S. Hornsby died on January 15, 2009 in a car accident near Crozet, Virginia. He was 28.  Following his graduation from the University of Miami, in 1977, Hornsby returned to his hometown of Williamsburg, and played in local clubs and hotel bars. In 1980, he and his younger brother (and songwriting partner) John Hornsby moved to Los Angeles, where they spent three years writing for 20th Century Fox. Before moving back to his native southeastern Virginia, he also spent time in Los Angeles as a session musician. In 1982 Hornsby joined the band Ambrosia for their last album Road Island and can be seen in the band's video for the album's single "How Can You Love Me." After Ambrosia disbanded, he and bassist Joe Puerta performed as members of the touring band for pop star Sheena Easton. Hornsby can clearly be seen in the music video for Easton's 1984 hit single "Strut."
Question: Did he ever play in any other bands?
Answer: In the spring of 1974 Hornsby's older brother Bobby, who attended the University of Virginia, formed the band "Bobby Hi-Test and the Octane Kids"

Problem: Background: Motion City Soundtrack was an American rock band that formed in Minneapolis, Minnesota in 1997. The band's line-up consisted of vocalist and guitarist Justin Pierre, lead guitarist Joshua Cain, keyboardist Jesse Johnson, bassist Matthew Taylor, and drummer Tony Thaxton.
Context: After signing with Epitaph, they recorded three new songs with the bands Reggie and the Full Effect and Ultimate Fakebook for a triple split EP which was never released. The new songs were added to the second release of I Am the Movie, which was released via Epitaph on June 24, 2003. This was a wider release than the initial release since they were now on a label. Using funds from the label to pay for the recording sessions, the band re-recorded several songs on the album to match their original vision. During this time, the band visited the United Kingdom for the first time in 2003 while on tour with Sugarcult, followed by performing at Warped Tour 2003. The band continued to tour heavily into the next year, with US dates alongside Rufio, Mae, and Fall Out Boy, Simple Plan, MxPx, and a European trek with Sugarcult, the All-American Rejects, Limbeck as part of the "Totally Wicked Awesome Tour". During this time, the band also filmed music videos for the singles "The Future Freaks Me Out" and "My Favorite Accident". The group began accumulating significant buzz, and were regarded as a must-see act on the Warped Tour 2004.  The band joined Blink-182 for touring stints in Europe and Japan throughout 2004, at the recommendation of that band's bassist, Mark Hoppus. Cain invited Hoppus to produce Motion City's sophomore album, and he accepted. That album, Commit This to Memory, was recorded at Seedy Underbelly Studios, a suburban home converted into a studio in Los Angeles' Valley Village region. It was written partially in their hometown of Minneapolis and in Los Angeles, during a period in which Pierre was seeking treatment for alcohol abuse. Commit This to Memory was the first album by the band to feature material crafted by each musician in the group, as previous releases had featured songs written in the years prior to each member joining. In addition, the band also had more time and funds create the album. During its recording process, Motion City embarked on their first headlining tour, The Sub-Par Punk Who Cares Tour 2004. By the end of 2004, the band had played over 270 shows.  Commit This to Memory, which was leaked to file sharing websites months before its official debut, saw release on June 7, 2005, peaking at number two on Billboard's Independent Albums chart. Pierre estimated that by 2015 the album had sold nearly 500,000 copies. The band's music videos found regular rotation on networks such as MTV2, and the band also performed on Late Night with Conan O'Brien. However, their mainstream breakthrough brought detractors, and they became a target for critics of pop punk: "[the band was] frequently characterized as the sort of ultra-commercial punk poseurs who water down the genre to the point of drowning it," wrote Michael Roberts of Westword. The group continued to tour "incessantly," attracting larger crowds. They began the year with the inaugural Epitaph Tour, alongside Matchbook Romance and From First to Last. It was followed by dates on the Warped Tour 2005 and the Nintendo Fusion Tour with Fall Out Boy, Panic! at the Disco, and The Starting Line, which was their largest nationwide tour to that point.
