The ASOT600 show at Madison Square Garden was already big, just due to the fact that it was part of Armin van Buuren's massive "A State of Trance" 600 worldwide tour. That night also saw Ferry Corsten and Markus Schulz debut their new supergroup, New World Punx, and their forthcoming single "Romper" got a debut that night. If you're a fan of their solo work, you'll definitely notice that "Romper" is a bit darker than either of their bodies of work. They admittedly tried to recreate the feeling of old school rave sounds in this one, and it works, which Markus Schulz explained to Rolling Stone: "We began working collectively in the studio, paying tribute to past rave classics. It's a throwback to those old, hard dance rave melodies. . . 'Romper' is one of those tracks where people just want to go crazy and party."

You can preview "Romper" over on Rolling Stone, and purchase it via New World Punx Recordings on June 10.

UPDATE "Romper" has been given away as a free download.
