After what seemed like a long wait for Imogen Heap fans, the British singer recently released her third solo album, Ellipse. She retains the same style - a melding of electronica-style instruments, standard pop forms and an organic sound - that earned her a Grammy nomination for Best New Artist with her 2005 album Speak For Yourself.\nThe album kicks off with the lead single, "First Train Home." This song is probably the most radio-friendly on the album, with a nice, conventional pop beat that will not intimidate any casual listeners. But Heap sprinkles personal touches throughout the song, such as at 2:44 when she sings, "So what, you've had one too many ..." During that verse, she lets her instruments out of their proverbial cages, enveloping the listener's ears in an avalanche of sound, which sets the tone for similar moments throughout the album. Another of these moments occurs during "Canvas," when she uses possibly every instrument in her kit to explore many different melodic ideas while the vocals largely take a backseat.\nLyrically, Heap's main strength on Ellipse is her ability to discuss familiar topics with insightful words, giving a feeling of originality to what should be a clich
