Shine was a various artists compilation album series released by PolyGram TV in Britain from 1995 to 1998, centering on indie rock, largely from new British bands (several American bands, like Green Day and Dinosaur Jr. appeared sparingly).
 The series began in 1995 to capitalize on the Britpop scene.
 In total, there were ten Shine albums, plus a 'Best of '97' compilation and a final 'Best of Shine' in 1998.
 The series ended in the late 1990s as the Britpop era passed.
Two Rock (Irish: "Binn Dá Charraig" ; archaic: Black Mountain; "Sliab Lecga " (meaning "Mountain of Flagstones" )) is a mountain in Dún Laoghaire–Rathdown, Ireland.
 It is 536 m high and is the 382nd highest mountain in Ireland.
 It is the highest point of the group of hills in the Dublin Mountains which comprises Two Rock, Three Rock, Kilmashogue and Tibradden Mountains.
 The mountain takes its name from the two granite tors that lie to the south-east of the summit.
 From the summit, which is called Fairy Castle, there are views of much of the Dublin area from Tallaght to Howth to the north while Bray Head, Killiney Hill, the Great Sugar Loaf and the Wicklow Mountains are visible to the south.
 The summit area is mostly shallow bog while ferns and gorse cover the lower slopes.
 The mountain is also an important habitat for red grouse.
Skid Row is the name of two rock bands; for their discographies see:
Asian Kung-Fu Generation Presents: Nano–Mugen Compilation 2006 is a compilation album released by Asian Kung-Fu Generation on July 5, 2006, to advertise their sixth annual Nano-Mugen Festival.
 The album features one song from each of the twelve groups — seven Japanese bands, three American bands, and two English bands — who performed.
The Zolas are a Canadian indie rock band based in Vancouver, British Columbia.
 They are signed to Light Organ Records.
 The core of the band is duo Zachary Gray (vocals/guitar) and Tom Dobrzanski (piano), with other musicians supporting them live and on record.
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.
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".
Daniel James "Dan" Hall is an Australian musician from Melbourne who has been in two rock bands, Taxiride and Airway Lanes.

 They released their debut album, "In Vino Veritas" in May 2008 with its lead single, "Don't Let Go", chosen as iTunes' 'Single of the Week'.
Green on Red was an American rock band, formed in the Tucson, Arizona punk scene, but based for most of its career in Los Angeles, California, where it was loosely associated with the Paisley Underground.
 Earlier records have the wide-screen psychedelic sound of first-wave desert rock, while later releases tended more towards traditional country rock.
