Tura New Music’s iMprov series presents experimental and exploratory improvisation at bar Four5Nine once a month on a Monday night. This month we present two performances by Rome-based guitarist Mike Cooper, a UK-born specialist in free improvisation, blues and folk musics, oft-exploring the sonic spaces shared by all of these genres and more. Cooper will be joined in a second set by an ensemble of local musicians who will have been working extensively with him throughout his week-long residency in Perth. To open the night, the avant-rock free improvisation trio of BOCKs will explore frenetic trio textures and angular interactions. Doors at 8pm, $5-$15 at the door (pay-what-you-want).
