During their May 2 show at the House Of Blues In Boston, MA, Testament were joined onstage by Exodus frontman Steve “Zetro” Souza for a performance of “Over The Wall.” You can see fan-filmed footage of that below. Notably, Souza used to perform “Over The Wall” during his stint in the pre-Testament band Legacy. The latest performance was part of Testament, Exodus, and Death Angel’s “Bay Strikes Back” tour, which was recently extended.
