Bay Area alto saxophonist Steven Lugerner brings his Jacknife band, with pianist Larry Willis, trumpeter JJ Kirkpatrick, drummer Michael Mitchell, and bassist Josh Thurston-Milgrom into the KPFA performance studio to play pieces from the album “Jacknife: The Music of Jackie McLean.“ Tony Ferro engineers the live radio concert. In the second hour, violinist Mads Tolling visits with host Derk Richardson, introducing us to the music of the new San Francisco String Trio, which also includes guitarist Mimi Fox and bassist/vocalist Jeff Denson. And … it’s a Pink Moon night.
