Astro Can Caravan is an unconventional mix of large ensemble post-Sun Ra cosmic jazz, Magma-influenced Euro-fusion and Herbie Hancock/Miles Davis-styled avant-jazz funk. The uncanny mesh of horns (trumpet, trombone), winds (sax, oboe, clarinet), guitar, bass, synthesizer and four percussionists, in addition to being unusual when transposed to the context of space rock, creates some undeniably astounding altered states of consciousness if listened to for extended periods of time. Astro Can Caravan were formed in 2001 in Kuopio in Finland by Otto Eskelinen, Pharaoh Pirttikangas, Tomi Kosonen and Tuomas Eriksson. The band has gone through a lot of personnel changes ever since, with at least 35 people that have played in ACC in some line up or another.
