This is not the Imogen Heap of Frou Frou. This is Imogen Heap solo, in her enchanting debut "I Megaphone." So don't expect silky, slinky trip-hop -- Heap opts for a darker, more raw kind of music that reflects the pain in the songwriting. Sort of a Tori-Amos-meets-Fiona-Apple sound, but with a spirit all its own.
