He adds that "Sirens" and another album track, "Infallible," are both "very melodic and beautiful songs." the recording of "Lightning Bolt" began with sessions in early 2012 after the blitz surrounding Cameron Crowe's 2011 "Pearl Jam Twenty" documentary and was finished during sessions at Los Angeles' Henson Recording Studios earlier this year. "Especially when we were finishing up," O'Brien says, there was a sense of "unity, everybody pulling together, and there was a joy about what we were doing. The songs have a lot of drama they're good at that. But there wasn't a lot of drama from the [process], just a lot of everyone enjoying." "I think it's a great representation of their work right now," O'Brien says of "Lightning Bolt." "If you like Pearl Jam, you'll love this. And if you haven't listened to Pearl Jam in awhile, I think it's going to bring you in. That's the whole idea."
