full_context: Document 1: Don't Let It Go to Waste: Don't Let It Go to Waste is the debut album from Matt Willis, released on 20 November 2006. The track "Who You Gonna Run To" features Imogen Heap on vocals.
Document 2: Fear and Whiskey: Fear and Whiskey is the fourth studio album by English rock band The Mekons. It was released in 1985 and marked a dramatic shift in their sound following a short hiatus. It is universally viewed as their masterpiece by fans. It is credited as being the first alternative country album, as it blends the band's previously-established punk rock style with a country music sound. The album was initially released by Sin Records to significant critical praise and commercial success. However, due to Sin's small capacity for production and distribution, the album then remained largely unavailable until it was rereleased in 2002 by Quarterstick Records, a subsidiary of Touch and Go Records.
Document 3: Hey Kid: "Hey Kid" is the second official single from Matt Willis, released on August 14, 2006. It is taken from Willis's debut solo album "Don't Let It Go to Waste". "Hey Kid" also appears in the 2006 teen film "John Tucker Must Die" and the action packed teen film "Alex Rider:Stormbreaker", and therefore will be on both the films soundtracks.
Document 4: The Mekons: The Mekons are a British-American rock band. Formed in the late 1970s as an art collective, they are one of the longest-running and most prolific of the first-wave British punk rock bands. Through the years, the band's musical style has evolved, incorporating aspects of country music, folk music, alternative rock and occasional experiments with dub. They are known for their raucous live shows. These days, The Mekons are often described as a post-punk, cowpunk and/or alt country band. The band is currently based in Chicago.
Document 5: Punk rock: Punk rock (or "punk") is a rock music genre that developed in the early to mid-1970s in the United States, United Kingdom, and Australia. Rooted in 1960s garage rock and other forms of what is now known as "proto-punk" music, punk rock bands rejected perceived excesses of mainstream 1970s rock. Punk bands typically produced short or fast-paced songs, with hard-edged melodies and singing styles, stripped-down instrumentation, and often political, anti-establishment lyrics. Punk embraces a DIY ethic; many bands self-produce recordings and distribute them through informal channels.
Document 6: Up All Night (Matt Willis song): "Up All Night" is Matt Willis's debut single as a solo artist. It was released as a single on 22 May 2006 and appears on his debut album, "Don't Let It Go to Waste". Its style marks a move towards more rock-influenced music than the songs Willis released when performing as part of Busted and could possibly be categorized as stadium pop.
Document 7: Boiled in Lead: Boiled in Lead is a rock/world-music band based in Minneapolis, Minnesota, and founded in 1983. Tim Walters of "MusicHound Folk" called the group "the most important folk-rock band to appear since the 1970s." Their style, sometimes called "rock 'n' reel," is heavily influenced by Celtic music, folk, and punk rock, and has drawn them praise as one of the few American bands of the 1980s and 1990s to expand on Fairport Convention's rocked-up take on traditional folk. "Folk Roots" magazine noted that Boiled in Lead's "folk-punk" approach synthesized the idealistic and archival approach of 1960s folk music with the burgeoning American alternative-rock scene of the early 1980s typified by Hüsker Dü and R.E.M. The band also incorporates a plethora of international musical traditions, including Russian, Turkish, Bulgarian, Scottish, Vietnamese, Hungarian, African, klezmer, and gypsy music. Boiled in Lead has been hailed as a pioneering bridge between American rock and international music, and a precursor to Gogol Bordello and other gypsy-punk bands. While most heavily active in the 1980s and 1990s, the group is still performing today, including annual St. Patrick's Day concerts in Minneapolis. Over the course of its career, Boiled in Lead has released nearly a dozen albums and EPs, most recently 2012's "The Well Below".
Document 8: Sex Pistols: The Sex Pistols were an English punk rock band formed in London in 1975. Although they initially lasted just two and a half years and produced only four singles and one studio album, "Never Mind the Bollocks, Here's the Sex Pistols", they have been called one of the most influential acts in the history of popular music, having initiated the punk movement in the United Kingdom, and inspired many later punk and alternative rock musicians.
Document 9: Busted (band): Busted are an English pop rock band from Southend-on-Sea, Essex, consisting of James Bourne, Matt Willis and Charlie Simpson.

A show Willis admitted going on purely to boost his music career.
Document 15: Folk punk: Folk punk (known in its early days as rogue folk) is a fusion of folk music and punk rock.
