So far having seen over 300 concerts and hoping for many more... I was eight years old and my first concert was KISS - Destroyer Tour in 1979 at the now sadly gone McNichols Sports Arena http://en.wikipedia.org/wiki/McNichols_Sports_Arena in Denver, CO. The arena had a great sound and atmosphere for concerts. Especially metal shows. The way it was built into a hill side made it like a bowl down into the ground of the hill side. That gave it good acoustics in my opinion. I saw many many great bands in oncert at the venue. Due to becoming out of date for sporting events by 1999 it was closed and demolished. I personally think they could have turned it into an awesome performing arts and concert hall venue. However, the site now hosts the new Mile High Stadium for the Denver Broncos. My second concert wasn't long after when I got to see Beatlemania in 1980. AC/DC For Those About To Rock Tour, with Fastway fronting the show, in 1981 at the same McNichols Sports Arena was my third concert and from there it was concert heaven from then til now! \m/ Judas Priest - Screaming for Vengeance Tour was my fourth concert at the same arena and I believe they were fronted by Uriah Heep. \m/ Good times!
