Lonerism: Lonerism is the second studio album by the Australian rock band Tame Impala, released on 5 October 2012 by Modular Recordings.  Like the band's debut studio album, "Innerspeaker" (2010), "Lonerism" was written, recorded, performed, and produced by Kevin Parker, with live member Jay Watson contributing on two tracks.  Recorded mostly in Perth, Australia, and Paris, France, "Lonerism" builds on the psychedelic sound of its predecessor by featuring fewer guitars and more synthesisers and samples. Parker attempted to incorporate his love for pop music into his songwriting for the record through catchier melodies.  Many tracks feature ambient sounds recorded by Parker with a dictaphone.  The album's theme of isolation is reflected in the album cover, featuring an image of a fenced-off Jardin du Luxembourg in Paris.

In Flight (Linda Perry album): In Flight is the first solo album by singer and producer Linda Perry, released in 1996.  It was produced by Bill Bottrell (Sheryl Crow, Michael Jackson).  Perry re-released the album in 2005 on her own record label Custard Records.  The re-release contains original videos from the singles "Freeway" and "Fill Me Up".  Perry says that Interscope, her record label in 1996, which had been hoping for something a little catchier than "In Flight", didn't promote the album, and the disappointing sales rattled her.  "My gut feeling that I relied on failed me. . . .  I was devastated", Perry says.
