Watched PinkPop on tv yesterday. A short review: Millionnaire (belgian group, seriously deranged singer), Macy Gray (dressed in pink, great band, great voice), Lamb (intrigueing tshink-ploink-ploink-squeek-thud with attitude) and Gomez (noisy yet melodic; these guys look creepishly normal!) were pretty good; Alien Ant Farm (yuk), System Of A Down (yukketie) and Rammstein (yukketie yuk) sucked all the way.
(Hate to admit it but: Lenny Kravitz sounded pretty funky too)
