Query: Great stuff!

I attended the concert in the early 80's that this group put together. Very good sound, ive got 90% of the Return to Forever music and found this to be a wonderful, laid back, expanding form of enjoyment! The drummer is indeed good, and Gayle Morans vocals are a pleasure (will need to hear more of her work in the near future). Anyone hesitant, try out samples on CDNow and see what you think. I dont think you will be disappointed, im glad that the group was able to put this collaboration together before their eventual demise...
