FINALLY! Finally, a group of artists who had the good idea of bringing in an album that includes previously unreleased or demos, "B-sides", the B-side or unreleased tracks from albums that have appeared in countries foreigners. Fans of the group will be pleased to listen to these 15 "small treasuries" circulating on the Web. I had already heard some but I had a pleasant surprise at hearing certain songs in other versions. So when a second installment of this kind? Because the group was and still is very prolific. It is a true gift that the group offers its fans! Thank you!
