See if you can watch this video of a mankini-sportin' Steven  Tyler bangin' away in a drum circle in Maui ... and NOT stare at his  drumstick.

Impossible, right????!

Anyway, we obtained this  incredible footage of the Aerosmith singer layin' down a beat during one of  those hippy drum circles usually reserved for Venice Beach ... or Matt  McConaughey's house.

Word on the street is ... the hot chick in the  background is Tyler's rebound chick ... which sorta makes sense since there have  been reports he broke up with fiancee Erin Brady.
