Tre Diablos were a short-lived side-project of Pantera members Dimebag Darrell, Vinnie Paul and Rex Brown. They recorded a single track, a cover of Heard It on the X by ZZ Top, for the ECW Extreme Music compilation whilst Pantera were on hiatus in 1998. Their name, Spanish for "Three Devils", is a reference to ZZ Top and their album Tres Hombres.
