Meshuggah is a Swedish five-piece experimental metal band formed in 1987. The band comprises founding members vocalist Jens Kidman and guitarist Fredrik Thordendal, drummer Tomas Haake, rhythm guitarist Mårten Hagström and bassist Dick Lövgren. Meshuggah first attracted international attention with the 1995 release Destroy Erase Improve for their fusion of death metal, thrash metal and progressive metal. On the album Chaosphere, released in 1998, the band used fast tempo with Thordendal's typical free jazz-like solos. With their 2002 album Nothing, Meshuggah started to use eight-string guitars with two extra low strings and incorporate downtuned, slow, groovy riffs. In 2004 and 2005, Meshuggah experimented with one 21-minute song on the I EP and a "one song album" Catch Thirtythree separated into 13 sections. The latest album, obZen, was released in 2008.   Wikipedia
