ALTERED STATES
There are four different bands named Altered States, listed in order of popularity: a Japanese free/noise jazz / avant-prog group from the 90s, an 80s gothic rock band, a Bass music production trio from Manchester and a psychedelic rock band from Dallas. 1. If pure musicianship is the guiding criterion, Altered States are arguably one of the greatest guitar/bass/drums trios in the history of rock, which may strike some as an overstatement but the evidence is there for anyone willing to seek out the band's Japanese label releases.
Kazuhisa Uchihashi
Kazuhisa Uchihasi (内橋和久, Uchihashi Kazuhisa) is a Japanese guitarist involved in free improvisation music. Born in 1959 in Osaka, Uchihashi began to play the guitar at age 12, playing in various rock bands, though he later studied jazz music. In 1988 he joined the band First Edition, and in 1990 formed the band Altered States. He was also a member of Otomo Yoshihide's Ground Zero from 1994 to 1997.
Filament
There is more than one artist with this name:
1. An onkyo experimental band from Japan
2. An American electronica/indie rock band from Detroit, Michigan. 1. Filament, consists of former Ground Zero members Otomo Yoshihide and Sachiko M, two of the defining artists of the onkyo music movement. In contrast to the dense, "chopped up", genre-hopping style of Ground Zero, Filament explores minimalist free-improvisation, concerned often with narrow-variations in tone and timbre usually without rhythmic structure or more than the slightest fragments of melody.
