''   To date , the band has sold nearly 32million records in the United States and an estimated 60million worldwide . Pearl Jam has outlasted and outsold many of its contemporaries from the alternative rock breakthrough of the early 1990s , and is considered one of the most influential bands of that decade .

Pearl Jam were inducted into the Rock and Roll Hall of Fame on April 7 , 2017 , in their first year of eligibility .
