New York City duo ASTR recently cut an Encore! Sessions, where they performed a few new songs. You can watch the premiere of 'Operate' from those sessions above.

The group has been making the promotional rounds lately for its recently released EP 'Varsity.' They stopped by Annie Mac's BBC show yesterday and played a new track, 'Part of Me,' which you can listen to here.

But if you can't get enough of 'Operate,' check out Chainsmokers' remix of the cut below. Personally, we really dig this version.
