Chris Whillock's series of free albums (with printables) bring you some of the best SID recordings ever made: 24/96 lossless, noiseless FLAC, recorded with an 8580 and a 6581 for an amazing lush sound, that's also crisp. And some of the filter effects need to be heard to be believed.
DO NOT WORRY THAT IT SAYS THE CDs ARE SOLD OUT
They are digital downloads. The "Sold Out" was to make sure you could download it from a link on the page instead of having to register through C64Audio.com's cart system.
