You check us on OKAYPLAYER last week?  the single was given some premiere treatment by them:

"If you have never heard of Brownout, that may be because it is the Clark Kent alter-ego to the instrumental powerhouse called Grupo Fantasma. And those cats you should have heard of; they just backed the GZA’s non-stop live performance of Liquid Swords at Bonnaroo and they are just generally the sh*t (no Brownout jokes, please). This jawn “Flaximus” displays their sound at it’s biggest and boldest, incorporating latin funk and psychedelic elements into a musical answer to the question, What if the Wu-Tang Clan was a marching band?"
