This kick ass garage band based in Monrovia-Arcadia CA. Their music is sensational to everyone's ears. You hear them and you fall in love and you think, "Its too bad you can't marry music." Then you listen a little more and you think, " It's too bad you can't have sex with music." They are influenced by rock legends like Led Zeppelin, Nirvana, The Beatles, Heart...., Megadeth, etc. Pyrotechnics is the shit.
