Ween fans have come to expect the unexpected from this act, but even diehards will be thrilled by the sheer musical schizophrenia of "La Cucaracha," the band's debut for Rounder and first album in four years. Only in Ween's world can the good-ole-boy bluegrass of "Learnin' to Love" comfortably sit next to the lewd garage rock of "My Own Bare Hands" and the cheap, stoned reggae of "The Fruit Man." Elsewhere, the band continues mastering the expression of its softer side, from the '70s AM radio love song "Sweetheart" to the alternate-universe smooth jazz of closer "Your Party" (with David Sanborn on sexy sax). In between, Ween walks its trademark annoying/captivating tightrope with panache (the odd noises on the effervescent "Blue Balloon," the faux mystic, out-of-tune "Spirit Walker") but never forgets to rock out, particularly on the 11-minute brain scrambler "Woman and Man." —Jonathan Cohen
