I'd obviously love Cosmosis, but frankly the audio quality of the material Bill used for his Retro v1 and v2 is atrocious - some of the tracks that I know were released on CD were 'sampled' from vinyls or DAT without any correction, so they're full of cracks, pops and hiss. No care whatsoever was taken to bring all the tracks to similar volume level and tonal (frequency) balance, so if that was to be the case for Digital Reprints release then I hope it won't happen...
I'm betting on Solar Fields!
