After 25 years of neo-hippie jams, squealing harmonicas and millions of records sold, the question still stands: Why did these guys name themselves Blues Traveler? Their sound, as this anthology proves, has never owed much to the blues. They're far more influenced by classic rock and '70s radio pop: Little Feat, Dixie Dregs and, of course, The Grateful Dead. No matter. What you get here is a sprawling mix of hits, deep cuts and oddities. Hardcore fans will take more interest in the second disc; that's where the rare stuff lurks, like the radical remix of "Run-Around" steeped in electronica.
