2. Pearl Jam - Title Unknown
Pearl Jam have kept a relatively low profile these past couple of years. Sure, they released a documentary and played some huge shows to celebrate their 20th anniversary, but they haven't released a new album since 2009, and they haven't done a real American tour since early 2010. During that time, Eddie Vedder has focused on his solo career, drummer Matt Cameron reunited with Soundgarden and Jeff Ament and Stone Gossard have worked with their side bands. They have been picking away at new Pearl Jam songs, though. "[We're] maybe halfway there," Vedder recently told Rolling Stone. "We're taking our time." A new album much later in the year seems like a strong possibility, but don't be shocked if it winds up being 2014.
