There’s nothing like former membership of a boyband for making a chap take himself seriously. The debut album by former Busted singer Charlie Simpson’s new project is a fizzy riot of earnest, cod-existentialist lyrics, crunching guitars and sampled voiceovers pondering Einstein and black holes. It’s fine, if you like that sort of thing. But hopefully, Charlie’s pop mojo hasn’t been discarded forever. Busted were fun, Charlie, and that’s nothing to be ashamed of.
