dweller2 I was going to suggest Wishbone Ash's Argus for the way-cool and melodic dueling guitars, but you beat me to it, so here goes: Frank Zappa's first CD was a double, Apostrophe and Overnight Sensation. He absolutely had his best musicians during this era. The instrumental title track to the former was written for the ex-Cream bassist Jack Bruce, and he romps. Jean-Luc Ponty appears on violin, and George Duke asks the question, "Why Does It Hurt When I Pee?" , with references to "The toilet seat", and certain anatomical parts feeling like a "Pair of maracas". Zappa's guitar work also superb, as are his compositions, and we learn about "The Slime oozing out of your TEEVEE set".
