Ariel Pink has become markedly more conventional since his early cassette-only recordings, when by his own admission he couldn't actually play – "I had no verifiable talent, no instruments, nothing. I was just completely disturbed," he told this paper in 2006. But it's all relative: for all that his second album for 4AD is full of normal pop sounds and melodies, it remains deeply odd. Kinski Assassin could have come from one of the early Julian Cope solo albums; Schnitzel Boogie revisits the lo-fi years with the chorus that repeats the phrase "I need a schnitzel"; Symphony of the Nymph sounds like Visage's Steve Strange recounting sexual fantasies to a therapist. But then there's the seemingly straightforward and glorious soft pop of the title track. Mature Themes poses questions of the listener: is this pop? Is this for real? Is he taking the mick? It will likely infuriate as many as it delights, but no one could dispute the singularity of Pink's vision.
