Query: Heavy & beautiful days

Grand Funk Railroad...it means a lot to me. Those were the days of my youth, I grow up with that rock music, Mark Farner's fine rhythmic patterns, Mel's exploding and thundering bass, Brewer's precise and brutal drums work...I think I will never forget that energy, that very unique live performance taken from some concerts held that hot summer around the East Cost (only the sleeve photograph is relevant to the Atlanta Pop Festival). This CD it's a must...about the remastering work, the drums is better defined than the vinyl, so too the guitar work...the bass, instead, is less powered (and Schacher used to set West Amps at "10"). The best tracks on it, in my opinion, are "In need" and "Mark says allright"...incredible energy and passion.
