Imogen Heap

Early MySpace sensation and current Twitter obsessive Heap is almost better known for her Internet savvy than for her music, but there's plenty to admire in the Grammy-nominated, electronica-favouring singer's style. Here she's rounding off her 'Reverb' season at the Roundhouse with a live performance, where you'll hear the whole of her new album 'Sparks' and plenty of eccentric pop favourites.
