The Beach Boys are an American rock band, formed in Hawthorne, California in 1961.
 The group is considered to be one of the most critically acclaimed, commercially successful, and widely influential bands of all time.
 Their co-founder and principal composer, Brian Wilson, is widely considered one of the most innovative and significant songwriters of the late 20th century.
 With record sales estimated at over 100 million, they were one of the few American bands formed prior to the 1964 British Invasion to continue their success, and among artists of the 1960s, they are one of few central figures in the histories of rock.

The Gumball Rally is a 1976 film directed and co-written by Charles Bail about a coast-to-coast road race.
 It was inspired by the Cannonball Baker Sea-To-Shining-Sea Memorial Trophy Dash run by Brock Yates, which inspired several other films, including "Cannonball" (1976), "Cannonball Run" (1981) and "Cannonball Fever" (1989); as well as an actual event, the American Gumball Rally and Gumball 3000 international race.
G.a.s. Drummers was a melodic hardcore band formed in Jerez de la Frontera, Spain at the end of 1997 by three teenagers who stood out from their other students due to their colourful hair dies and their taste in the california punk rock bands such as Bad Religion, Operation Ivy, NOFX, Lagwagon, The Descendents etc.
 Original members from other small local bands Dani Llamas (guitar and vocals), Pakomoto (Bass and vocals) and Rafa Camison (Drums) started playing together and composing their own music and after one year of sending demos around the country they got put as the opening act for Swedish Punk Rock band Randy on their Spanish tour.
 A tour that took the band through the whole country helping a lot of Spanish kids discover that there were actually Spanish bands capable of sounding as good as some of their favorite American bands.
 This lead immediately the band to sign to a young record label called Slide Chorus Records a young emerging record label from Madrid which would start releasing albums for other Spanish Punk Rock bands.
 This first release titled Proud To Be Nothing hit the streets at the end of 1999 and was presented on their first European tour which covered Spain, Great Britain, France and the Netherlands amongst Spanish punk rock legend[P.P.M.
Lostprophets were a Welsh rock band from Pontypridd, Wales formed in 1997.
 Founded by lead vocalist and lyricist Ian Watkins, bassist (later guitarist) Mike Lewis, drummer Mike Chiplin and guitarist Lee Gaze, they were originally a side-project to hardcore punk band Public Disturbance.
 They were also part of the Cardiff music scene.
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".
