Kind of droney-psychedelic-moody pop/rock, sometimes pretty good but dreadfully emo when not done well. So named because jack shit happens on stage during shows, they just stand there staring at their shoes (a bit of a caricature, obviously) while they play.
Tame Impala are overrated. They're one of those bands I keep thinking I should like, but then I go back and check them out one more time and it's always, "Nope, still not doing it for me."
Although I'm not sure either would fully qualify under Pio's rigorous standards, The Brian Jonestown Massacre and Wooden Shjips both kick the shit out of the bands ethan listed, although I do kind of like Yuck.
Just posting this as a PSA since this guy is probably a regular poster here.
