Rat Sound, the original punk rock sound company

Rat Sound Systems is the original punk rock sound company. Started in LA in the early 80s, it was a stalwart of the early LA punk scene (posters: it did happen). Starting in the 1990s, Rat Sound has been supplying sound for some of rock’s biggest acts. They even went corporate, with a client list including Paris Hilton.
Since May 2006, founder Dave Rat, who mixes the Red Hot Chili Peppers for the audience, has been keeping a tour blog.
Those of you who (like me) are interested in audio nerdery may be interested in the Sound nerd speak section of Dave’s blog. (e.g. drum fills, subs, input lists, amplifiers, the Grateful Dead’s wall of sound)

You may also read about the technical evolution of sound systems, from humble beginning to the Rat Trap 5 cabinet of the 1990s and the L-Acoustics V-DOSC and Microwedge of today. Also of interest: Dave’s Roadiepedia.
