While My Guitar Gently Weeps series has gone on to sell over 600K albums since it's inaugural release. The Best of combines the very best tracks from the previous three albums, previously unused tracks in the series and also tracks from massive artists who have enjoyed a recent re-emergence including the Eagles (770K albums sold in 2007) and Robert Plant & Alison Krauss (430K albums sold in 2007) giving the album huge currency and profile from these massive stars. Has the strongest track listing of the series yet - including exclusivity on the Eagles track with this group rarely clearing for compilations.
