Please answer the following question: Read the bio below and try to give details on ruins -lrb- japanese band -rrb- 's: - years active - past members - origin - genre - name - background - label - current members - associated acts Bio: ruins is a japanese music duo composed only of drummer/vocalist tatsuya yoshida and a bass guitarist -lrb- there have been four such bassists in the band 's history -rrb- . the group , formed in 1985 , was supposedly intended to be a power trio ; the guitarist , however , never showed up to the band 's first rehearsal so the group remained a duo . the music touches on progressive rock , jazz fusion and noise rock . the french progressive rock band magma is the group 's most important influence , to such an extent that ruins ' original lyrics are written and sung in an invented language which , at first glance , resembles kobaian , the language invented by christian vander of magma . ruins ' material -lrb- which yoshida , who composes the majority of their pieces , writes out in score form -rrb- is generally of extreme complexity and thus is often described as inaccessible ; potential listeners may be bewildered by the band 's unrestrained yet disciplined approach . in addition to the '' prog rock '' label , the group 's music has also been described as '' math rock '' and '' zeuhl '' . that said , ruins ' style has consistently evolved since the band 's beginning , often changing according to the bassist that tatsuya was collaborating with at the time . ruins have collaborated with several other musicians , including prominent avant-garde figure derek bailey , auteur guitarist/multi-instrumentalist keiji haino and ground zero alumnus kazuhisa uchihashi . sasaki hisashi left the band in 2004 , and since then yoshida has been touring solo under the name ruins-alone -lrb- ruins alone -rrb- . he has also performed as sax ruins with alto saxophonist ono ryoko . he was chosen by matt groening to perform at the all tomorrow 's parties festival groening curated in may 2010 in minehead , england .
