They jam, therefore they am - as their horde (fest) of fans will attest. But Blues Traveler go further afield here. Make no mistake: They've got that boogie thing covered: "Carolina Blues", "Canadian Rose" and "Felicia" are prime BT radio fodder: heavy on harmonica pyrotechnics, bluesy romanticism and motormouth vocals. Yet, to their credit, they're branching out: "Business as Usual" owes a thing or two to Primus, some funky touches echo Little Feat and even one ballad chimes in the Cat Stevens mode. If some songs fall flat, it's not for lack of trying. Harp hero John Popper's lightning runs are amazing, and he crams in more words per second than any singer since Elvis Costello. Unfortunately, when you decode those sneaky little words, it's not always worth the effort.
