Cambridge-based improv collective Concrete Gazebo present their latest collection of open-hearted, quantum splice-downs, via Goldsmiths University label NX Records.

"Acid Heath" documents the ebb and flow of a collective in flux; online and in-the-flesh improv sessions form the raw material to be welded into new and fantastic forms by the group's hive-mind. Instruments falling into the pot this time around include a heavily effected Harmonic Art Handpan, the Yamaha PortaSound PSS-50, live-triggered field recordings, and mobile phone recordings of the jams themselves.

The result is a murky, atmospheric stew, at different times suggesting a sort of Fenland psychedelia, lof-fi krautock, or a deconstructed Broadcast.

When not making music, the band have organised free, open-to-all improvisation nights, "Under The Concrete Gazebo", since 2018.
