Its a stone groove without the first half nudity, though strategically covered by statues and uh...hands. The song kicks ass, dunno what a TK 421 is, but its a tease (what a tease) of the forthcoming 'Blue Electric Light' from Lenny in March. Its not the first time we've seen all of Mr Kravitz, but this time wasn't a wardrobe malfunction. Hope you enjoy it. Make sure you turn friends on to the many talents of LK.
