(Avant-Garde Jazz, Cool Jazz) [WEB] Jason Stein Quartet (Keefe Jackson, Joshua Abrams, Tom Rainey) - Lucille! - 2017, FLAC (tracks), lossless

https://jasonstein.bandcamp.com/album/lucille
Bass clarinetist Jason Stein's quartet explores a combination of Stein's original compositions as well as uncommonly heard compositions by such luminaries as Lennie Tristano, Thelonious Monk, and Charlie Parker. Stein's work on the bass clarinet is expanding the instrument's comfort zone and capabilities and his quartet uniquely showcases his ability to seamlessly work within both more traditional jazz idioms as well as free improvisation.

Jason Stein continues to curve a niche in the jazz world, but it's not what you might assume. Listeners straightaway assume that he is an idiosyncratic outlier because his sole instrument is the bass clarinet. We've grown accustomed to saxophonists like Eric Dolphy and David Murray doubling on the bass clarinet. Stein's constancy to this one woodwind instrument, like Germany's Rudi Mahal, is unequivocal, yet the sound of the instrument doesn't define his trajectory.
Stein plots an unconventional and idiosyncratic path with his quartet. A path tread by the original voices of Thelonious Monk and Lennie Tristano. Like their previous release The Story This Time (Delmark, 2011), the music covers music by the aforementioned giants and their followers, plus three originals by Stein. Joining the bass clarinetist is saxophonist Keefe Jackson and fellow Chicago stalwart, bassist Joshua Abrams. Drummer Frank Rosaly (now living in Europe) is replaced here by Tom Rainey.
The Tristano connection is heard on two covers, "April" and "Wom," plus music by his disciple Warne Marsh, "Marshmallow." The Stein/Jackson combination recalls the Marsh/Lee Konitz adaptations. Stein's original composition "Halls And Rooms" uses that partnership as a jumping off point, before taking us down a twisting road, saxophone and bass clarinet incited by Rainey's chattering clatter. The combination of horns quickly sheds any inclinations of pretentiousness. Even Charlie Parker's "Dexterity," rendered with Jackson on contrabass clarinet, doesn't get swamped by the heaviness of the woodwinds. The pair perform a sort of sleight of hand, performing at an escape velocity not imagined by their instrument makers. What is unique here is just that, the quartet's expression is not limited by the choice of instrumentation, it is actually liberated by it. Monk's "Little Rootie Tootie" is given a whitewater rapids treatment with both clarinets barking and biting multi-phonic shouts. Same for "Roused About," Robert Hurst III's dedication to Monk's longtime saxophonist Charlie Rouse. Jackson (back on tenor) and Stein play a joyous cat-and-mouse game with the theme as Abrams and Rainey dance the night away. This is one dynamic session.
