Unreleased work from the glory days of the Peter Brotzmann Chicago Tentet – a legendary free jazz ensemble that's playing here at the height of their powers! The group have a vibe here that's wonderful – both as playful and as sinister as the title might imply – stretched out to a performance that's almost 20 minutes in length, and which almost has a sort of cinematic sense of dynamism at times – although still with all the unscripted energy that made the group so great. Brotzmann is in the lead on tenor, with Mars Williams on tenor and soprano, Ken Vandermark on baritone, Mats Gustafsson on alto, Joe McPhee on valve trombone, Jeb Bishop on trombone, Fred Lonberg Holm on cello, Kent Kessler on bass, and Michael Zerang and Hamid Drake on drums. The first-ever issue of this music comes in a limited one-sided record – with music on side a, and a silkscreen of Peter Brotzmann artwork on side B! LP, Vinyl record album

Mary Halvorson seems to expand her sound here a bit more than usual – not in that she's working with a large ensemble, or in any sort of too-ambitious ways – but just that she's mixing her very unique phrasing on the guitar with just the right blend of other instruments – all at a level that feels way more than just the sum of its parts! The sextet features work from Adam O'Farrill on trumpet, Jacob Garchik on trombone, and Patricia Brennan on vibes – the last of whom is especially great, and whose tones really do a lot to color the album and shape the sound. The trumpet's got a great presence too – trading nicely with the trombone – and titles include "Desiderata", "Collapsing Mouth", "The Gate", "Tailhead", and "Ultramarine". Plus, Laurie Anderson plays guest violin on "Incarnadine". LP, Vinyl record album

A very unique album from Hank Mobley – one that has him working alongside Milt Jackson, in an unusual format that mixes the soulful Mobley tenor with some well-crafted work on vibes! The "all star" title is certainly appropriate here – as Mobley and Jackson are joined in a quintet by Horace Silver on piano, Doug Watkins on bass, and Art Blakey on drums – almost bringing in an early Jazz Messengers sensibility to the record, but also hitting more of a looser, laidback blowing session approach. There's less of the tightness of other Mobley sessions from the time, and the record has the players really feeling each other out in the studio – with the sort of spontaneity you might hear in a Prestige or Savoy album from the time. Tracks are long, and titles include "Ultramarine", "Don't Walk", "Lower Stratosphere", and "Mobley's Musings". LP, Vinyl record album
