Amanda Blank is a Philadelphia rapper whose trump card in her early guest appearances with electro hip-hop collective Spank Rock was to talk in provocative detail about sex. As an attention-grabbing device it paid off, judging by the producer credits on her debut album. Diplo, Switch and TV on the Radio's Dave Sitek have all contributed, with some energising results - "Might Like You Better" will sound great in clubs, but Blank fails to make a lasting impression.
