Jake Brettell and Liam Nolan had known each other for three days when they began work on their debut album. It was freshers’ week, and they had proggy 70s Canadian pop band Klaatu on the record player, when they decided to start rapping over the top. The end result was Dr Marvelo & His Best Friend Corkie, Chinatown Slalom’s first song. Is “screwball prog-rap made by two first-year music tech students” a good elevator pitch? Perhaps not. But the shaggy, funny, tricksy songs featured on their debut long-player Who Wants to Be a Millionaire? are a rare example of an indie band in 2019 who don’t seem in thrall to the genre’s recent history.
