A box set documenting the October 2015 3-day event held at Porgy and Bess in Vienna for the 50th birthday of saxophonist Mats Gustafsson (The Thing, Fire! and innumerable duo/trio/ensemble formations) with a who's-who of collaborators invited to join in various formations.

Two drummers - Jim Black & Paul Lytton - and two trumpeters - Nate Wooley & Peter Evans - came together at the 53rd Ljubljana Jazz Festival to record these extended improvisations, demonstrating the phenomenal skill and compatibility of these outstanding players.

Nate Wooley and Paul Lytton continue their collaborations, extending their new duo recordings with live tracks from The Stone in NYC with Ikue Mori, and at Chicago's Hideout with Ken Vandermark.
