It can’t be said that Tool aren’t good to their openers. At the Tucson stop of their tour, the band brought out Intronaut guitarist Dave Timnick, who was celebrating his birthday that day, to join in on percussion when they played “Lateralus.” Maynard even sang “Happy Birthday” to him mid-jam. That’s one hell of a nice present. While the audio isn’t top notch, it’s still worth seeing. Intronaut vocalist/guitarist Sacha Dunable is keeping a tour diary for the LA Weekly, and it’s pretty inspirational to read about a band more used to playing small clubs talk about playing arenas.
