El Monstero, The Definitive Pink Floyd Tribute Experience, features some of the most talented musicians and singers of the St. Louis music scene. On lead vocals is Mark Thomas Quinn (of Joe Dirt and Celebration Day), joined on stage by guitarist Jimmy Griffin (of the Incurables and Celebration Day), guitarist Bryan Greene (of the Wyld Stallyns), bassist Kevin Gagnepain (of Stir, Shooting With Annie and Joe Dirt), percussionist John Pessoni (of Stir, the Urge and Joe Dirt), keyboardist Bill Reiter (of the Urge), and keyboardist Jake Elking (of Buz). Saxophonist Dave Farver (of Superjam and King of Pain) rounds out the group with standout backup vocalists Ermine Cannon, Tandra Williams and Melinda (Mindy) Mierek. El Monstero began performing in 1999 and has grown into both a holiday and summer tradition for fans of Pink Floyd in St. Louis and around the Midwest. The band spares no expense to create a visual and audio experience to compliment the depth of the music of Pink Floyd.
