This is the second iteration of Oregon, formed three years after the death of founder-member Collin Wallcott in 1984. Gurtu’s precise, invigorating percussion fits perfectly with the quicksilver guitar of Towner and the mobile basslines of Moore. On the opening 14-minute track, Towner’s ‘June Bug’, their collective empathy is immediately apparent, and Gurtu’s extended solo completely fits the band’s aesthetic and gets riotous applause.

Recorded by Germany’s South West Radio, this is one of the treasures to have been brought out of the past broadcast archive for international issue. The band often drew on its old collaborations, and here its earlier work with Jim Pepper is recalled with ‘Witchi-Tai-To’ in a version that nods slightly in Pepper’s direction, but is very much about where the band was at in 1990, with Towner’s emphatic but also beautifully delicate guitar taking the lead, and ushering a fine solo from Moore, before McCandless shines on soprano sax.

With 14 tracks spread over two CDs, many of them clocking in at around or above the 10-minute mark, there’s a feast of listening here, but the momentum never flags, and it’s often hard to remember that this is just a quartet, the sound is so full and the interaction so complete. Whether taking off on a free improvisation over a guitar motif (‘Waterwheel’), building on Towner’s self-duetting on piano and electric piano (‘Hand in Hand’), or building a spooky atmosphere with McCandless’ horns and Towner’s pitch-varied keyboard over Moore’s bass on ‘Leather Cats’, this sounds like no other group in jazz. For a fine set by this incarnation of Oregon, look no further.
