Pearl Jam had never been more popular than they were in early 1994. Armed with that sense of invincibility, the Seattle band set about taking on a concert industry behemoth.

In a bold move, Pearl Jam charged Ticketmaster with creating a monopoly after they gobbled up principal competitor Ticketron in 1991. This allowed Ticketmaster to pile on whatever it wanted in additional service fees, which Pearl Jam said was driving up the price for concerts. The group wanted to charge no more than $18.50 for tickets in 1994, with service fees of no more than $1.80. Ticketmaster balked, saying that they needed at least $2 in fees simply to cover costs.

Eddie Vedder and company weren't just paying lip service: They hired the Manhattan-based law firm Sullivan and Cromwell, and on May 6, 1994, filed an official complaint with the Justice Department, leading to testimony from bassist Jeff Ament and guitarist Stone Gossard before Congress.

Ticketmaster CEO Fred Rosen shot back: "If Pearl Jam wants to play for free, we'll be happy to distribute their tickets for free." Elsewhere, Time magazine referred to the anti-trust-focused legal battle as "Rock 'n' Roll's Holy War."

Pearl Jam ended up skipping a summer tour as the battle raged. That was no small thing, considering the huge reception the group's two most recent albums (1991's Ten and 1993's Vs.) had received. They tried, mostly for naught, to book into venues that weren't associated with Ticketmaster.

"Our band, which is determined to keep ticket prices low, will always be in conflict with Ticketmaster," Gossard asserted.

It was, however, for naught. The federal investigation was eventually dropped. Worse, really, was that Pearl Jam was eventually forced to book parts of their next tour with – you guessed it – Ticketmaster.

What exactly has changed, decades later? Not much. Ticketmaster, in fact, got larger still when it merged with event promoter Live Nation in 2010, becoming Live Nation Entertainment.

The dust-up led to one moment of levity when Vedder inducted Neil Young into the Rock & Roll Hall of Fame in 1995. A party planner put Pearl Jam's table next to Ticketmaster's at the ceremony, prompting Vedder to quip: "I predict a food fight by the end of the evening. I would recommend that the classy people scoot away, or join in! Maybe we should all join in, while we've got them right here!"
