Brilliant work from Jason Stein – a Chicago player who's been making some mighty waves on the avant scene of late, and who really comes into his own with this album! Stein's part of the new generation of avant Chicagoans – players who have a strong knowledge of free jazz, but also opt for a bit more structure and swing too – the kind of modernism that emerged best at the cusp of the 60s, in the generation of Mingus, Dolphy, and Ornette! Stein plays bass clarinet here, and there's definitely a Dolphy vibe to the music – great long solo lines, stretched out and searching, but also still swinging too – thanks to these nicely-blocked rhythms from Josh Abrams on bass and Frank Rosaly on drums. Keefe Jackson also plays some mean tenor – and titles include "Laced Case", "Background Music", "Little Big Horse", "Hatoolie", "Gallop's Gallop", "Work", "Lennie Bird", and "Badlands". Another great one from the new generation of Delmark! CD

Natural Information Society have been a key force on the Chicago underground for a number of years – and here, they go back even further, to open the door to the legendary saxophonist Ari Brown – who joins the group on tenor! You might know Brown's music as a member of 70s spiritual group The Awakening, or his later solo albums – and his time-schooled spirit is a perfect match for the ensemble led by bassist Joshua Abrams, who also plays some guimbri on the set. Other players include Ben Lamar Gay and Josh Berman on cornets, Jason Stein on bass clarinet, Lisa Alvarado on harmonium, Kara Bershad on harp, Nick Mazzarella on alto, and Hamid Drake on congas and tablas – a group who work together with the richly organic vibe we always love in projects from Abrams. Titles include "Moontide Chorus", "Is", "Murmuration", "Wane", "Wax", "Immemorial", and "Stigmergy". LP, Vinyl record album

The Delmark debut as a leader from drummer Frank Rosaly – and a very unique little record! Rosaly's a player we've really dug on other folks' records, and his vision here at the helm is pretty darn great – a real change from some of the modes used by his avant Chicago contemporaries – almost more poetic at points, although filled with sharp edges throughout! The record was composed for use in a documentary about Chicago scrap recyclers working the alley of the city – and Rosaly brings a really human, personal sort of feel to his music – even though the overall approach is still based on improvisation between group members too. The lineup features James Falzone on clarinet, Jason Stein on bass clarinet, Jason Roebke on bass and cracklebox, Keefe Jackson on tenor and bass clarinet, and Jason Adasiewicz on vibes – which adds some particularly great tones to the metallic narrative. Rosaly also plays a bit of percussion, piano, and electronics – and titles include "Adrian", "Bedbugs", "Driven", "Yards", "Wet Feet Splashing", "The Dark", and "Tragically Positive". CD

A really fantastic album from bassist Joshua Abrams – a set that may well be his greatest to date – and that's saying a lot, given all the other work he's given us in recent years! The double-length set has Abrams working with this lineup of improvising jazz talents, but in a way that's very rhythmic, and very organic – slow-building songs that almost seem to mix jazz with inspiration from gamelan music, but with very spiritual currents overall – music that builds slowly and flows to the cosmos – almost in a way that reminds us of the seminal "On The Beach" by Phil Cohran & The Artistic Heritage Ensemble! Yet Abrams is very much in his own territory here – working with a lineup that features the leader on guimbri, Lisa Alvarado on harmonium and gongs, Mikel Avery on tam-tam and gongs, Ben Boye on electric autoharp and piano, Hamid Drake on tabla and tar, Ben Lamar Gay on cornet, Nick Mazzarella on alto saxophone, and Jason Stein on bass clarinet – with every member of the ensemble also performing on flutes. The sound is incredible – music to build a bridge to the heavens – and titles include "In Memory's Prism", "Finite", "Shadow Conductor", and "Agree". CD

A double-length set that showcases the ever-growing, ever-evolving talents of drummer Quin Kirchner – working here in a variety of settings with help from some other great talents on the Chicago scene! Most of these tunes have a core sense of structure – and even when Quin is improvising more freely, he still finds a way to swing – working here on conventional drums, other percussion instruments, and even a bit of kalimba too – alongside a mix of players that includes Nick Broste on trombone, Nate Lepine on tenor and flute, Nick Mazzarella on alto, Jason Stein on bass clarinet, Greg Ward on alto, Rob Clearfield on piano, and Matt Ulery on bass. Many numbers have a spacious, ambitious vibe – almost spiritual jazz, of a quality that really has us respecting Kirchner more than ever – and the double space of the album is really needed to allow this majestic message the room to unfold properly. Titles include "Ecliptics", "King Korn", "Jupiter Moon", "Horizons", "At This Point In Time", "Bata Chop", "Pathways", "Star Cluster", and "Moon Vision". CD

Beautiful music from a group that features familiar players from the world of improvised music, but coming together here in a very different way! Joshua Abrams leads the group, and he's playing guimbri instead of his usual bass – a lighter stringed instrument used with global currents that set a pace for a very organic sound throughout – quite rhythmic at times, but still opening up with plenty of freely improvised moments – from a group that includes key contributions from Lisa Alvarado on harmonium and effects, plus drums from Mikel Patrick Avery, bass clarinet from Jason Stein, and soprano sax from the legendary Evan Parker! The setting is quite an unusual one for Parker – even though the date was recorded at the Cafe Oto in London – and with a set like this, it's clear that the growing power of Abrams' music is starting to have a larger global impact. The set features one long track – "Descension – Out Of Our Constrictions" – spread over the double-length set. LP, Vinyl record album
