Pearl Jam rose above the legions of grungy alt-rockers littering the early '90s to become the most popular and enduring American rock & roll band of their time. Unlike many of their Seattle brethren, Pearl Jam, as a collective, were never signed or affiliated with an indie label -- founding members Stone Gossard and Jeff Ament both were veterans of Green River, one of the first major bands on Sub Pop, though -- and in an age defined by irony, they were unflaggingly sincere. Much of this earnestness stemmed from Eddie Vedder, a lead singer of uncommon charisma and passion who helped the group's arena rock moves seem intimate. Vedder's emotional acuity remained a touchstone for Pearl Jam throughout the years, giving the band's unpredictable business moves, such as their mid-'90s battle with Ticketmaster, and embrace of controversial causes genuine heft. The group's inclination to follow a winding path meant that by the time Pearl Jam left the 1990s, they were no longer ruling rock music the way they did at the start of the decade -- a period when Ten, Vs., and Vitalogy sat at the top of the charts as they racked up millions of sales -- but were left with an enormous and devoted cult that allowed the band the freedom to experiment while remaining true to their rock & roll ideals.
