Ah yes, Tool circa 1991. The band was a year old at this point, Paul D'Amour was still the bassist and played a weird Ovation bass, and fans would not yet know the hardships of waiting over 10 years for a new album.
What you're about to see is Tool's performance on October 7, 1991 at The Club With No Name in Hollywood, opening for a band called Too Free Stooges. According to Metal Insider, the latter group features Porno For Pyros bassist Martyn LeNoble before he was in the band. So there's a weird little tidbit of information.
For reference, the live tracks off Tool's 1992 Opiate EP were recorded on December 31, 1991, meaning these shows pre-date even that.
