Hot Air splits nearly equally between absurdist, political, jump-cut, Dada wailers (A specialty on Ron Johnson. See also: The Membranes, A Witness, Pigbros, The Shrubs, The Noseflutes, and Bogshed.

Their live shows were immersive multimedia events, with the band playing within projections of experimental films made especially for them. Apparently they’ve reformed, inspired by the ease and immediacy of laptop production (gigs in the 80’s often had to wait while their film maker spliced broken reels back together in the tour van), so look for their gigs if you live in the Leamington area.
