Gaz Coombes, Danny Goffey and Nigel Godrich are Hot Rats
The band are set to make appearances at a clutch of festivals this summer including Glastonbury next Friday (June 26), Truck Festival on July 26, the Reading And Leeds Festivals (which takes place on August 28-30) and at Bestival on September 12.
This is the second time the Supergrass pair have formed a side-project. They took on the roles of Duke Diamond and Randy Hoo Ha (Combes and Goffey respectively) in their previous guise The Diamond Hoo Ha Men when bassist Mick Quinn suffered a broken back after a fall in 2007.
The Hot Rats plan to release their debut album in the autumn.
