Almost a year after Soundgarden's break-up, in summer 1998, Cameron was invited by rock-colleagues Pearl Jam to drum on its U.S. Yield Tour after the band's drummer Jack Irons left due to the touring scheduling conflicting with his health issues and a desire to spend more time with his family. Cameron had worked with members of the band before on the Temple of the Dog project and had helped them record some early instrumental demos in 1990. Cameron said, "I got a phone call out of the blue, from Mr. Ed Ved, Stoney and Kelly (Curtis, Pearl Jam's manager). I was ambushed. It was really short notice. He called and said 'hey what are you doing this summer?'" Guitarist Mike McCready said, "We knew him from being around the same scene and seeing him on tour. It had a lot to do with it. We knew he was a normal cat too, a normal guy." Cameron learned over 80 songs in two weeks. He was hired on an initially temporary basis, but soon, during the tour, he was invited to become a full-time member. Cameron stated, "The guys made me feel real welcome and it wasn't a struggle to get it musically, but my style was a little bit different, I think, than what they were used to. And they've been through so many different drummers, I don't even know if they knew what they wanted. So, I just kind of played the way I played and then eventually we kind of figured out what worked best for the band."
