I like anything from 1970-1991, with a few exceptions. There are some shows that are rough around the edges like 1986 when Jerry came back from his coma. My favorite shows are from 1972, 1978, 1985 and 1989. I LOVE Brent's sound in '85. Anything after 1991 is not worth listening to, in my opinion. Frankly, I prefer to only listen to anything pre-Vince Welnick. I hated Vinces sound and playing and the only reason I recommend 1991 is because those summer shows with Bruce Hornsby were really amazing. Anything with just Vince is shit, in my opinion.
My first show was 6-26-87, Alpine Valley, WI. Truly amazing experience. I was hooked from that day on.
