Binaural (album): Binaural is the sixth studio album by the American alternative rock band Pearl Jam, released on May 16, 2000 through Epic Records.  Following a full-scale tour in support of its previous album, "Yield" (1998), Pearl Jam took a short break before reconvening toward the end of 1999 to begin work on a new album.  During the production of the album, the band encountered hindrances such as singer Eddie Vedder's writer's block, and guitarist Mike McCready's entrance into rehabilitation due to an addiction to prescription drugs.

Backspacer: Backspacer is the ninth studio album by the American alternative rock band Pearl Jam, released on September 20, 2009.  The bandmembers started writing instrumental and demo tracks in 2007, and got together in 2008 to work on an album.  It was recorded from February through April 2009 with producer Brendan O'Brien, who had worked on every Pearl Jam album except their 1991 debut "Ten" and 2006's self-titled record—although this was his first production credit since 1998's "Yield".  Material was recorded in Henson Recording Studios in Los Angeles, California and O'Brien's own Southern Tracks Recording in Atlanta, Georgia.  The music on the album—the shortest of the band's career—features a sound influenced by pop and new wave.  The lyrics have a more optimistic look than the ones in the politic-infused predecessors "Riot Act" and "Pearl Jam", something frontman Eddie Vedder attributed to the election of Barack Obama.

The music on the record featured a diverse sound, including songs influenced by folk, art rock, and experimental rock.
