NJ Congressman Bill Pascrell, Jr. issued a statement on Wednesday demanding answers from Ticketmaster about outrageously high ticket prices for Bruce Springsteen & the E Street Band‘s upcoming tour.

“Today I’ve demanded answers from Ticketmaster on the monopoly’s role in the Springsteen tour fiasco where fans were charged upwards of $5,000 for seats,” Pascrell wrote in a letter published to social media. “Hard-working Americans who are fans of Bruce and other popular entertainers should have the ability to enjoy live entertainment without ticket-sales practices that rip off consumers.”

He continued with a litany of questions about Ticketmaster’s role in the tour and the company’s “dynamic pricing” system: “How many shows will be played in venues, owned, operated, or exclusively booked by Ticketmaster?” he asked. “For how many of these shows is Ticketmaster the primary… or… exclusive ticket seller?”

Congressman Pascrell also demanded “specific data and any details that support” Ticketmaster’s claim that “these prices and formats are ‘consistent with industry standards for top performers,’” asking, “Does your company inform customers as to how many tickets will be available for sale, at what time, and how they will be priced?”

According to Ticketmaster, only 1.3% of total tickets so far have sold for more than $1,000, with a total of 11.2% tickets designated to change price based on demand, per Consequence. The company also claimed that 56% of tickets were sold for less than $200, and 18% for less than $100. Jon Landau, Springsteen’s longtime manager, added, “In pricing tickets for this tour, we looked carefully at what our peers have been doing. We chose prices that are lower than some and on par with others.”

The reasoning behind Ticketmaster’s dynamic pricing system is that it helps artists and other entities involved in actually putting on events to recapture some of the revenue that for years has gone to ticket scalpers through the secondary market. “As the resale ticketing market has grown to more than a $10 billion dollar industry over the past few years, artists and teams have lost that revenue to resellers who have no investment in the event going well or any of the people working behind the scenes to bring the event to life,” Ticketmaster said. “As such, event organizers have looked to market-based pricing to recapture that lost revenue.”

A rep for Ticketmaster expressed the company’s willingness to engage with critics and adjust its practices, saying, “We appreciate and share Congressman Pascrell’s passion for improving the ticketing industry and look forward to continuing our dialogue with him.”

Congressman Pascrell previously authored legislation called the Better Oversight of Secondary Sales and Accountability in Concert Ticketing, or the BOSS Act, after Springsteen. He has also argued that the federal government should separate Ticketmaster from Live Nation, who acquired the ticketing giant in 2010. Live Nation is the world’s biggest producer of live music events and owns and operates of a significant portion of major venues in the U.S. A recent exposé on John Oliver‘s Last Week Tonight examined criticisms of the live music conglomerate for allegedly “[strong-arming] venues into using Ticketmaster” and “[retaliating] against or [threatening] venues” that did not use its services.
