My very first real "rock concert" was Humble Pie and Jo Jo Gunne in the Sam Houston Coliseum, and I've been going ever since. Check out
http://rockinhouston.com/ for an incredible archive of pix from concerts in Houston (and few elsewhere).
Some of my most memorable were:
Led Zeppelin (Coliseum and Summit)
Black Sabbath (Coliseum, Jeppesen Stadium, Verizon, the Woodlands - as "Heaven & Hell", but c'mon, wither goest Tony goest the Mighty Sabbath - and many points in between)
ZZ Top (too many times to name, including the Summit, Jeppesen Stadium, the Astrodome)
Rolling Stones (in the Astrodome with ZZ Top and the Fabulous Thunderbirds . . . plus at least three other shows in Houston))
Genesis (in the Music Hall, with Peter Gabriel playing the Lamb Lies Down on Broadway in its entirety)
Pink Floyd (Jeppesen Stadium)
Sex Pistols (Randy's Rodeo in SA)
Ramones (Armadillo World Headquarters - twice!)
Night of the Hurricane (in Hoffeinz Pavillion - Dylan, et al)
CSNY (Jeppesen Stadium)
The Clash with Joe Ely (Cullen Auditorium)
Yo La Tengo (Warehouse Live - surprisingly, the loudest show I ever attended)(
Tool with The Melvins (Astro Arena)
Tool (at least six other times)
Incubus (3x at the Woodlands - one of my favorite live bands)
Grateful Dead (25+ times, including AstroWorld, Manor Downs on July 4, Golden Gate Park)
U2 (4x)
Parliament/Funkadelic (the Summit, Halloween 1976)
The Who (first concert in the Summit - plus numerous other occasions)
