Being a fan of Jons music for years, I felt the need to step in here and correct what a couple other reviews have said, that this set is a collection of poor quality mp3s...because it's not.It clearly states on the cd cover that it is a collection of the original Turquoise & Crimson mp3s that have been fully mastered. Which means they took the tracks and MASTERED them to cd quality. The mastering was NOT done from an mp3 source either, and anyone who bought the original mp3 downloads also knows this - as the original mp3s were of pretty bad quality. The tracks on this cd are not of bad quality & if you played the original mp3s side by side with this disc and couldn't hear the difference - you are freakin' DEAF!Great album, great songs. And like others have said - the tracks that later appeared on Nude are here in different versions. Definatley a must have for any VAST fan.
