Excitement about the band bubbled onto the Internet a few days before the show, along with an Isthmus review of the group's new album, Free Your Mind.
Before long, only a handful of tickets were left.
And then there were none.
Meanwhile, Cut Copy admired the foliage on Madison's east side.
The show's openers were very solid. Madison DJ Nick Nice started the night right, as usual, and Greek artist Larry Gus made a lasting impression with his fusion of noise-pop, dream-pop and neo-disco.
The gap between Larry Gus and Cut Copy was probably the most annoying part of the night. But it was fun to admire Cut Copy's massive arsenal of gear.
There was time to admire the crowd, too.
Fans were curious if the band would play any of their old material, such as the hits from their 2008 album, In Ghost Colours.
