Madonna will debut songs from the new disc, which features collaborations with Justin Timberlake, Timbaland, Pharrell Williams and Nate “Danja” Hills, April 30 at Roseland Ballroom in New York City.

The concert will also be broadcast live on MSN.com.

V Cast Music and Vodafone customers who download the full-song, ringtone or ringback tone of Timbaland’s mobile underground remix of “4 Minutes” will have a chance to win a barcoded ticket to the performance.

Winners will receive tickets on their mobile phones, which will admit them and one friend to the show.

For info on dowloading the song, users can text MADONNA to 8933 or visit VerizonWireless.com/Music.

Other fans who want to see the performance will need to line up outside of the venue to receive tickets on a first-come-first-served basis.

Hard Candy will be released internationally April 28 and in the U.S. on April 29.
