What Is It? A hyper-imaginative and unconventional jazz trio formed by Australian trombonist Chris Greive, Aberdonian guitarist Graeme Stephens and American drummer Chris Wallace, all Edinburgh residents.

Who are these guys? Three of the best musicians around on the Scottish guitar scene – Greive is a regular in the SNJO trombone section, Stephen leads his own bands as well as working with fellow Aberdeenshire pipes-and-saxes wiz Fraser Fifield, and Wallace is the drum power behind several bands, including Loose Grip.

What does it sound like? Intriguing and unusual compositions making inventive use of the sound and textures of the three instruments, interspersed with fearsome bouts of freely improvised fireworks.

What are they up to now? They have just issued a superb album with German saxophonist Silke Eberhard added to the line-up, but their Fringe outing features the trio paying their tribute to Led Zeppelin – they promise Zep classics given the distinctive NeWt treatment in an hour of adventurous, high-energy music making. Should be grand fun, too.
NeWt Trio Play Led Zeppelin, The Jazz Bar, 226 0000, 10, 12 Aug, 7.30pm, £6 (£5). Part of the Edinburgh Jazz & Blues Festival.
