Late as ever, I've just discovered YouTube (basically Flickr for video). Their slogan is 'Broadcast Yourself', but people mainly seem to be broadcasting cool music videos:
1) Prince's new single 'Black Sweat' is fantastic, and very much like the old times again - analog synths, Linn Drums. The video is here, and another great new Hendrix-esque tremolo-tastic song 'Fury' from SNL here.
2) Holy crap! Rick Wakeman playing awful muzak really really fast here
3) Vangelis synthporn, plus comedy piano playing and loads of toffs running about here (stick with it, there's a CS80 and ARP 2500 & 2600s later)
4) Giorgio Moroder and Phil Oakey's finest hour here
5) Clyde Stubblefield drumming with James Brown in 1968 here
6) 808 State's 'Cubik here
7) Some dudes in a bedroom with an 808 and a 303 here
8) Lots of Aphex Twin videos here, particularly this great oldie.
9) And a whole mess of Kraftwerk here
10) Iggy and the Stooges doing 'TV Eye' live in 1970 here
(Thanks to Matrix Synth for pointing me in the right direction)
