Query: Gram Live and Real!

Many of the reviews address the sound quality (which is quite good and typical of the time) and the continuity of the recording. Having been one of the lucky few audience members at more than one of the intimate simulcast radio concerts at the Ultrasonic Recording Studios in Hempstead, LI, NY in the early 1970's, via the now defunct 92.7 WLIR-FM, this is extremely good and Gram is in top form. For those too young to have been there or remember, this was the typical format for those of us Long Island kids, to hear live music outside of a club or concert venue. Listening to these live, was a truly special event, anxiously awaited, and shared with our friends and favorite substances. You will get to hear Gram as we heard him over the radio in 1973. This is history as we heard it and as it happened.(Although we didn't know it at the time.) Gather some friends, play it LOUD, and listen to some "Cosmic American Music". Enjoy! That's how we did it.
