The spaced-out beats and cinematic atmospherics of trip-hop have found their avatar in downtempo pioneer Richard Dorfmeister of Kruder & Dorfmeister and Tosca fame.

Despite his wry attitude, sharp opinions and a Viennese predilection for half-adozen coffees at a sitting, Dorfmeister remains the epitome of laid-back.

But a quick glance at his resume shows that Dorfmeister has been a busy man.

In addition to commanding a steady schedule of DJ gigs, running the G-Stone label with Peter Kruder and recently becoming a father, there's Tosca, which has become his primary musical concern.

A collaboration with Rupert Huber, Tosca has been remarkably prolific.

Since its legendary F*** Dub 12-inch breakthrough of 1996, the duo have released four full-length CDs (one double), numerous 12-inches and a couple of compilations of multi-remix meditations on a single track.

The variety of each Tosca project sets out to belie the myth of the sameness of the downtempo sound.

Tosca's most recent CD, J.A.C., is the pair's strongest and most-varied release yet. Featuring a squad of top-notch vocalists, including the great Egyptian expat Samiah Farah and former Galliano singer Earl Zinger, there are occasions when it even speeds up. But it never strays too far from Tosca's trademark dubbiness.

From 5pm, £8/£6/free before 9pm.
