Like the Caribou set that was ending when theirs began, Tame Impala’s big-stage almost-headliner stand was a study in head-nod immersion. They play psych-rock so sweet and soft and gooey and funky that it becomes chillout-tent material. But the standout, at least for me, was them bringing “‘Cause I’m A Man” to the stage for only the second time. “‘Cause I’m A Man” is a mid-’80s Madonna power ballad dressed up as Rundgrenesque studio-prog. It’s only been in the world a few days and it’s already my favorite Tame Impala song. Tame Impala, and Parker in particular, seemed a bit nervous in the second-from-headliner spot, but it’s impossible to sound nervous when singing a song this smooth.
