In comparison to the psychological acting style and emphasis on method acting that was popular at the time, the La MaMa workshop focused on the other side of acting: externalized, kinetic techniques. The fifteen members of the La MaMa Troupe had workshops in movement, voice, and acting for five hours a day, five days a week. These workshops included hundreds of different exercises, which are best represented by "Hair," a La MaMa show that transferred to Broadway in 1968. "Village Voice" critic Michael Smith wrote on "Hair"'s Broadway opening: "O'Horgan has blown up Broadway." "Hair" brought international acclaim to O'Horgan and the La MaMa performance style.
