New recordings have emerged of Sun Ra and his Arkestra performing at the 13th International Jazz Piano Festival in the Polish city of Kalisz in 1986. It’s compiled from recently rediscovered recordings of the concert, which were apparently lost in a basement for the last three decades. Remastered by Marcin Cichy of Ninja Tune, they're being released by Lanquidity Records as a limited edition yellow vinyl LP on 26 October.

Live In Kalisz is available for pre-order on Bandcamp now. You can listen to the album track “Improvised” below.
