tatu... urk! that's where I draw my line. lady gaga does awesome live performances. I remember laughing quite a bit when she ran around "bleeding" on stage at some MTV shit and they filmed the expression some rapper or whatever the fuck in the audience. "WUTS DIS CRAZY CRACKER CHIK DOIN? dis some fuckin picasso shit right here".. oooh priceless. Then she hang herself on stage. She gives a more metal performance than even mayhem does nowadays.
