I love when a current band covers a current song. It's so 1960's. Here's two big acts covering the big indie band of the year. Katy Perry and The Kooks get their hands on some MGMT and bring their acustic guitars along. It's fun.
As far as getting super indie cred covering, The Ruby Suns get the coup for their spot on english transition of El Guincho's island anthem Palmitos Park. The best covers don't copy the original they indulge in it. The Ruby Suns gave El Guincho a big hug and we reap the benefits.
