Sean Conly and Michaël Attias

Jazz-tribute projects often roll out a threadbare welcome mat, promising an all-Ellington or -Monk program, or a rundown of a canonical staple. But in recent years, an alt-repertory movement has bubbled up, with artists reframing the work of underappreciated outliers or tightening the focus to a single deep-catalog classic. The first of two sets at this performance by saxist Michaël Attias and bassist Sean Conly will focus on pieces from 1977’s magical Soapsuds Soapsuds—an album of duets by saxist-trumpeter Ornette Coleman and bassist Charlie Haden—which captures the earthy lyricism of that pairing in a boldly stripped-down setting. For set two, Attias and Conly switch to free improv, as documented on Think Shadow, a 2012 OutNow Recordings release marked by both outré textural exploration and sparse, songlike dialogue.
