This murky - faintly menacing - advert seems to be still trying to sell Marc Bolan as an underground act, even on the eve of his pop superstardom. You can barely see his pretty face, let along any glitter on the cheekbones.
The musician, barely identifiable as Marc, is totally self-absorbed, wrapped up his own sound and his own cool. He's not meeting the gaze of a potential audience.
It's totally out of step with the direct appeal to tweenage girls of the song itself ("I don't mean to be bold but may I hold your hand?" - courtly love vassalage reframed in 12-bar boogie), the luscious cloying caramel-sweetness of the "la la la la-la la-la" hook / fade-refrain ...
Likewise the cover for Electric Warrior is "heavy". Face hidden by long frizzy hair... guitar perpendicular and phallic... The musician is lost in the auto-erotic swirl of the awesome noise he's generating, inwardly focused on his playing, his masturbatory mastery of the instrument, barely aware of the audience... Bolan is presented as guitar-hero (a warrior armed with electricity - that massive amplifier behind him blasting out pure power). He's an active noise-maker not a passive object of desire, a fey plaything. It could be a cover for a Paul Kossoff solo record.
