Oh, Good Grief! isn't Vince Guaraldi's classic piano-trio recordings of his "Peanuts" favorites--for those, try the soundtrack to A Boy Named Charlie Brown. But it is a 1968 "re-imagining" of several of those favorites with Guaraldi on both piano and electric harpsichord, and Eddie Duran's electric guitar joining Carl Burnett's drums and Stanley Gilbert's bass. The sound is unfamiliar but the groove is unmistakably Guaraldi's, and it'll grow on you after your ear adjusts. For purists, the "Great Pumpkin Waltz" and "Rain, Rain Go Away" are a return to Guaraldi's trademark acoustic lyricism. It's only 28 minutes, unfortunately.
