The U.S. debut solo album by Frou Frou vocalist Imogen Heap is a captivating record that fuses innovative electronic soundscapes with a strong female voice. If "Goodnight and Go" -- a lilting, pulsating, and hit-ready concoction -- and the alluring, synthesized pop of "Hide and Seek" are the most direct numbers, experimental numbers like the ethereal "Have You Got It in You?" plus the rhythm-fueled "Headlock" and "Loose Ends" suggest Heap has written and produced the finest electro/alt rock CD of 2005. By the time the eclectic, innovative "Closing In" arrives late in the cycle of Speak for Yourself, there's little denying it. by John D. Luerssen
