Where music geekery and typographical geekery intersect: Rock That Font looks knowledgeably at the typography of notable album covers.
Hans Reichel (previously) is a man of many talents. His own site (flash/sound) is fun (often funny) and chock full of agreeably wacky sounds, but can take some time to navigate. Reichel hasn't made it easy for you if you happen to be in a hurry. You may well get stuck somewhere and just give up. That'd be a shame, though, cause you'd miss getting acquainted with the guitars he makes and plays. Or how he designs fonts. The mixing board shenanigans are not to be missed (once you get past those curious little fellows in the brown hats), plus you can sorta kinda play his daxophone yourself. And of course conduct your own little ensemble of meercats when one of them finally comes out of hiding and says "Hallo! Play with me".
