In a seven-page ruling obtained by Rolling Stone, U.S. District Judge Arun Subramanian refused to toss the DOJ’s claim that Live Nation coerces artists into using its concert promotion services if they want to perform at venues in the company’s vast network of major amphitheaters.

A federal judge in New York denied Live Nation Entertainment Inc.’s attempt to narrow the Justice Department’s antitrust case seeking to break off Ticketmaster Entertainment Inc. after the companies merged more than 15 years ago.

The Justice Department, along with 30 state and district attorneys general, sued Live Nation and Ticketmaster last year, claiming the related companies exercise monopolistic control over U.S. performance venues.

Concerts included in Ticketmaster's latest two-for-one promotion mainly take place in the Los Angeles area at various venues.

Ticketmaster is offering a 2-for-1 St. Patrick's Day deal on tickets for Brad Paisley, Halsey, and Willie Nelson and Bob Dylan's Outlaw Music Fest.

Ticketmaster is celebrating St. Patrick's Day with a rare discount offer to some of the biggest concerts of the year. For a limited time, music fans can take advantage of Ticketmaster's 2-for-1 deal to get two tickets for the price of one at participating shows.
