July 18, 2026

El Monstero began its theatrical presentation of the band’s music in 1999. The band is comprised of St. Louis natives Mark Thomas Quinn (lead vocals/guitar/lap steel guitar), Jimmy Griffin (lead vocals/guitar), Kevin Gagnepain (bass/vocals), Bryan Greene (electric and acoustic guitar), John Pessoni (drums/vocals), Bill Reiter (keyboard/vocals), Jake Elking (keyboard), Dave Farver (saxophone), Erminie Cannon, Tandra Williams, and Kirstin Johnson (vocals).

El Monstero focuses on the Gilmore/Waters era of Pink Floyd, but ventures into albums recorded both before and after that time in the band’s history. El Monstero delivers an audio and visual experience like no other combining pyro, massive theatrical props, aerial artists, innovative and interactive technology, special guest performers and fireworks.
