Grammy-nominated hard-rock band Disturbed will launch the Music As A Weapon IV Tour — a music, tattoo and lifestyle festival. The event also features a collection of the greatest tattoo artists from around the country offering their talents; an extreme sports complex where freestyle motocross, BMX and Skate teams will perform; a Technology and Gaming Zone; and a Vendor Village. Disturbed will be joined on the 38-city, nine-week trek, which kicks off Mar. 20 in Madison, WI, by Killswitch Engage on the main-stage and other acts to be announced on the second stage. Music As A Weapon is now taking submissions from tattoo artists and festival vendors. Go to www.musicasaweapon4.com for more information.
