The latest running of improvised music night Lume tomorrow at the east London café gallery Long White Cloud is a double bill of Nick Malcolm’s improvising trio Our Own Decay featuring the trumpeter plus vibist Corey Mwamba & drummer Simon Roth, plus the duo of bassist Olie Brice and singer Fumi Okiji. Next week it’s the turn of the duo Ti/om and Molino De Otoño, with May nights to include appearances by guitarist Ant Law’s quintet, trumpeter Andre Canniere, and the Lauren Kinsella quintet.
