by William Ruhlmann"I have my moments," John Popper declares, and many of them -- as harmonica player, singer, and lyricist -- are here, on an album that finds Blues Traveler stretching out much as they do on-stage. Popper is a man with a lot on his mind, but when he reaches "The Best Part," his verbosity approaches a Walt Whitman-like exuberance, and guitarist Chan Kinchla is right with him, contributing sweet fills here, Pete Townshend-style strumming there. And as for the rhythm work of bassist Bobby Sheehan and drummer Brendan Hill, as Popper says, "It's all in the groove."
