Fifteen years ago, the flashy harmonica and sly vocal delivery of John Popper helped cement a new subset of pop music. Picking up where the Grateful Dead left off, Blues Traveler's success and the formative H.O.R.D.E. tours they organized and headlined popularized dozens of bands like Phish, The String Cheese Incident and Widespread Panic. Now in the second half of its career, and after a few years of silence, Blues Traveler unfortunately isn't nearly as groundbreaking on !Bastardos! Recorded in Austin with former Wilco-ite Jay Bennett, the album, while dynamic, doesn't have any songs as blatantly catchy as "Hook" or "Run-Around" from 1994's Four. Breathtaking harmonica solos, one of the main reasons for listening to the band, are now as sparse as Popper's new waistline, replaced by odd organ fills and distorted electric pianos. The eerie yet playful arrangement of "What Could Possibly Go Wrong?" and the just-plain-strange sound collage of "The Children of the Night" are curiosities at best. It's hard to fault the band for not furthering the genre it helped to create, but as the band succinctly says on "That Which Doesn't Kill You": "The politics of lasting just a little bit longer/Is the art of living every day."
