@big_greg: The first Rock 'n' Roll colored vinyl album I saw and bought (in 1970!) was Dave Mason's great debut album, Alone Together (recorded by the legendary Al Schmitt.). Accompanying Dave are the all-star cast of Leon Russell, Chris Ethridge of The Flying Burrito Brothers,, Carl Radle of Derek & The Dominos, L.A. studio pianist Larry Knechtel, John Simon---here he is again!, Delaney & Bonnie, Rita Coolidge and Claudia Lennear, and the killer drummer-quartet of Jim Capaldi of Traffic, Johnny Barbata of The Turtles and soon-to-be Jefferson Starship, and Jims Gordon & Keltner. Wow! .
The Alone Together PVC is of the "marble swirl" variety (which looks like Silly Putty does after you have copied some comic strips ;-), which does look cool spinning. The sound quality is good, too. I have augmented a couple of albums I have on black vinyl with the one colored vinyl variant I love the look of, that being Coke bottle green: the new Los Lobos and Rodney Crowell albums. The B-side of the second disc in the Los Lobos album is blank, the space taken up with a cool-looking etching. Had to have it!
@tgilb: QRP presses LP's for some of the majors, too. They did The Band boxset that contains all their studio albums, for instance. Lots of companies got rid of their presses in the 90's, thinking LP's were gone and never coming back. Bet they now wish they hadn't!
