Simon Neil (Biffy Clyro) and Mike Vennart (Biffy live guitarist and formerly Oceansize) sat down with NME to tell NME about putting together their art-metal supergroup Empire State Bastard with the "marvellous" Naomi Macleoud of Bitch Falcon and "hero" Dave Lombardo of Slayer (who they also took to Greggs and Lidl). Here they also tell us what to expect from their debut album, what the future holds, and those long-awaited albums from Marmaduke Duke and Tippie Toes
