Well I don't know much about rory gallagher, in fact I knew nothing about him before christmas, but I know what I like, and this album is great.As I am new to rory's music, I can't compare the song selection or sound quality with his albums, but if this is poor, his albums must be mindblowing.
Great songs, with some amazing solos and a great run of five live performances at the end of disk 1. As for sound quality, I don't see what there is to complain about,everything sound crystal clear to me. Another nice feature, for any guitarists out there anyway, is the booklet. It may seem like a pretty insignificant thing, but in it rory talks about his influences,guitars and guitar techniques and equipment he uses etc.
Overall this is a great collection for a casual Rory Gallagher fan, or someone completely new to his music. It'll definately lead me on to buy some of his albums, and see what all the fuss is about.
