'J' has to be "Joe's Garage"! There can be no other!
This was the first Zappa album I ever heard and I remember listening to it for weeks almost nonstop (yes, my life was like that...not any more)! The story, the songs, the minute detail, the editing, the playing, the laughing of 'The Central Scrutinizer'...a perfect concept album based on the music industry. If you've ever been in a band, this is the album to listen to and hopefully you will laugh. If you're disgusted by this album, I think it's time you should look in the mirror...
Here is this MASTERPIECE on youtube...!! (unless you're in the UK...WAIT...you're British? you have money, well, at least 4 times more than me...go out and buy this one :-))
