Audiophile pressings of classic/iconic rock. These are some of the most influential rock recordings ever made. Mobile Fidelity Original Master Recordings and Nautilus SuperDiscs went to the original tapes and then half-speed mastered them. These are acknowledged to be among the "best-of-the best" black vinyl. Some are stamped "For Demonstration," meaning that they are early run or cherry picked. Most are mint. All are "excellent" or above. The selection includes Tull's Aqualung, Moody Blues Days of Future Passed, Rolling Stones Sticky Fingers, and more. The discs are individually priced from $30-$160.
