Yeah, I've got some as well. "Absolutely Free," "We're Only In It For the Money," "Hot Rats," "Waka/Jawaka," "The Grand Wazoo,"....all superb.
He didn't let up, either...transcendent stuff on later discs as well. Like anyone else, I like some songs better than others. If I was deserted on a desert island, with only one artist's work, there's no doubt who I'm picking..
I've considered getting a USB turntable and ripping some of the old vinyl to digital. As far as Zappa, I may just see what they get for his entire catalogue, in lossless files..
