JASCHA EPHRAIM His brilliant self-produced, self-titled debut, is the work of a formidable solo artist. The album alternates his songs, which explore subjects that range from riding on the back of a dinosaur to the Columbia space-shuttle disaster, with recordings of himself as a toddler talking into a tape recorder, prompted by his mother and grandmother, illustrating his effortless natural talent for music, wit, and celebrity. $12.49
