Any of you heard Tool's version of "No Quarter"? It's not your typical audiophile music, but if you are a fan of Led Zepplin, you really must give it a listen.You can check it out on Tool's Salival album. You can grab a sound byte at the link.
Warning: Don't play this if you're one of tose guys running compression horn tweeters with first-order crossovers. You'll spit the diaphragm right out onto the floor, shattering and shredding it into tiny pieces by the phase plug as it exits.
