I watched this show, at Aliso Niguel, it was freaking awesome. It inspired me so much that i went from playing guitar in Winter Drumline to playing Tenor drums in marching season, and marimba in my most recent winter drumline season :D
its because they practice at schools and the year before this was Los Alamitos because the assistant director for pulse (Richie Sebastion) was the LAHS band director and now its at a different school because Sebastion changed schools (i go to LAHS and it was sick seeing them all the time)
