Initially an instrumental group SILVER MOUNTAIN, formed in 1978, were based around the duo of bassist Pär Stadin and vocalist/guitarist Jonas Hansson. Amongst the band's earliest members were keyboard player Jens Johansson and his drummer brother Anders Johansson, both of whom joined YNGWIE MALMSTEEN. The debut 1979 single, 'Man Of No Present Existence', featured a line-up of guitarist Morgan Alm, bassist Ingmar Stenqvist and drummer MÃ¥rtin Hedener and SILVER MOUNTAIN added the Johansson brothers in 1982 from Jazz-fusion band SLEM.

SILVER MOUNTAIN's debut commercial release with the Johansson brothers came in the form of the track 'She Needs' on the 1982 GS Music compilation 'Skånsk Rock'. Both brothers quit to join YNGWIE MALMSTEEN after the 'Shakin Brains' album. There are bootlegs culled from jam sessions circulating that feature the Johansson brothers, Yngwie Malmsteen and Per Stadin from this period.

For the 'Universe' album SILVER MOUNTAIN added erstwhile NORDEN LIGHT singer Christer Mentzer and re-recruited Hedener on drums.

In mid 1986 SILVER MOUNTAIN changed vocalists from Mentzer to Johan Dahlström. Hedener also lost his place for the second time to new recruit Kjell Gustavsson.

Hansson pursued a solo project the JONAS HANSSON BAND with JOEY ALLEN PROJECT vocalist Stanley Rose, ex-ALCATRAZZ drummer Jan Uvena, and LEGACY and LIZZY BORDEN bassist Martin Andersson issuing the 1994 album 'No.1', 1996's 'Second To None' and a 1999 follow up 'The Rocks'. However, even by 1998 a full-blown SILVER MOUNTAIN reformation was heavily rumoured. 1999 found Anders Johansson performing on ACES HIGH's second album 'Pull No Punches'. SILVER MOUNTAIN, numbering Jonas Hansson, Anders Johansson, Per Stadin and Jens Johansson, finally released their reformation album 'Breakin' Chains', issued by the Japanese Avalon Marquee label, in the summer of 2001.

In 2006 Jonas Hansson released a further solo album, 'Valhallarama'. For this effort Hansson handled all aspects of the recording including guitar, vocals, all instruments, production, engineering, mixing and mastering. Unveiled in spring 2006, Pär Stadin and Anders Johansson featured in GEFF, the Hard Rock construct of singer Göran Edman, noted for a wealth of credits fronting the YNGWIE MALMSTEEN band, CROSSFADE, MADISON, KHARMA, XSAVIOR and GLORY amongst others, together with guitarist Ralf Jedestedt. Both Jonas Hansson and Marten Andersson contributed sessions on OVERDRIVE and LOCOMOTIVE BREATH guitarist Janne Stark's November 2006 MOUNTAIN OF POWER tribute collection.
