Puscifer (photo: Ian Young) Maynard James Keenan is many things:  singer, comedian, winemaker, jiu-jitsu practitioner.  And now he can add luchador to the list.  Maynard brought his alt-rock alter-ego Puscifer to The Fox Theater on Tuesday night, entertaining the sold out audience with lucha libre matches, various costumes and, of course, his signature sound.
