The band's third album Audio Secrecy, was recorded at the Blackbird Studios in Nashville, Tennessee with producer Nick Raskulinecz, who was the producer for the band's second album Come What(ever) May. and released on September 7, 2010 . Taylor stated that "Audio Secrecy is the summation of everything we want, everything we crave and everything we fight for...The dimensions go further than anything we've ever tried before. It's metal, rock, slow, soft, hard, fast, bitter, beautiful and most importantly, it's real. You can't get an album like this out of a band that doesn't exist. We're throwing caution out the damn window." Stone Sour played the first annual Rockstar Energy Drink Uproar Festival with Avenged Sevenfold and Hollywood Undead among others. Stone Sour set the release date of Audio Secrecy as September 7. Stone Sour were part of the Soundwave Festival in late February/early March in Australia 2011.

It was also announced that a Stone Sour live DVD will be released, filmed at the Brighton Centre in the United Kingdom. The band toured with Avenged Sevenfold, New Medicine and Hollywood Undead on the "Nightmare After Christmas Tour" 2011. On April 16, 2011, it was announced that bassist Shawn Economaki had left the tour for personal reasons.

Tori Amos (born Myra Ellen Amos, August 22, 1963) is an American singer-songwriter, pianist, and composer. She is a classically trained musician with a mezzo-soprano vocal range. Having already begun composing instrumental pieces on piano, Amos won a full scholarship to the Peabody Institute at Johns Hopkins University at the age of five, the youngest person ever to have been admitted. She was expelled at the age of eleven for what Rolling Stone described as "musical insubordination.
In May 2008, Amos announced that, due to creative and financial disagreements with Epic Records, she had negotiated an end to her contract with the record label, and would be operating independently of major record labels on future work. In September of the same year, Amos released a live album and DVD, Live at Montreux 1991/1992, through Eagle Rock Entertainment, of two performances she gave at the Montreux Jazz Festival very early on in her career while promoting her debut solo album, Little Earthquakes. By December, after a chance encounter with chairman and CEO of Universal Music Group, Doug Morris, Amos signed a "joint venture" deal with Universal Republic Records. Abnormally Attracted to Sin, Amos's tenth solo studio album and her first album released through Universal Republic, was released in May 2009 to mostly positive reviews. The album debuted in the top 10 of the Billboard 200, making it Amos's seventh album to do so. Abnormally Attracted to Sin, admitted Amos, is a "personal album", not a conceptual one, with the album exploring themes of power, boundaries, and the subjective view of sin. Continuing her distribution deal with Universal Republic, Amos released Midwinter Graces, her first seasonal album, in November of the same year. The album features reworked versions of traditional carols, as well as original songs written by Amos. During her contract with the label, Amos recorded vocals for two songs for David Byrne's collaboration album with Fatboy Slim, titled Here Lies Love, which was released in April 2010. In July of the same year, the DVD Tori Amos- Live from the Artists Den was released exclusively through Barnes & Noble. After a brief tour from June to September 2010, Amos released the highly exclusive live album From Russia With Love in December the same year, recorded live in Moscow on September 3, 2010. The limited edition set included a signature edition Lomography Diana F+ camera, along with 2 lenses, a roll of film and 1 of 5 photographs taken of Tori during her time in Moscow. The set was released exclusively through toriamos.com and only 2000 copies were produced.

Why was it highly exclusive?

Gnarls Barkley is an American soul duo, composed of singer-songwriter CeeLo Green and producer Danger Mouse. They have released two studio albums, St. Elsewhere (2006) and The Odd Couple (2008). St. Elsewhere was recorded on the Warner Music UK label, and contained their hit single "Crazy" which topped at number two on the US Hot 100, and topped the charts in the UK. It was also nominated at the 2007 Grammy Awards for Record of the Year, and was platinum certified for shipping over 1,000,000 records.
In early March 2008, the duo's second album, The Odd Couple, was leaked over the internet prompting the duo to push the release date up from April 8. In an interview with Entertainment Magazine, Danger Mouse said that he "knew it [the leak] was coming...every day, I expected to get a call saying it leaked, and eventually I got a call saying it leaked." On March 18, 2008, the album became available via download on the iTunes Store and Amazon MP3. Hard copies of the album were released on March 25. Prior to its official release, Green spoke to the album's anti-formulaic qualities, noting bluntly that "there's no formula to it," and that to expect the same wild success of St. Elsewhere is to neglect the ever-present "risk factor in any artistic endeavor." He called it something of an "act of faith" - a true, earnest attempt to create and disseminate a piece of art to those who would seek out its conception. They appeared as the musical guest on the April 12, 2008 episode of NBC's Saturday Night Live. They were supposed to be in a Digital Short parodying amateur music videos according to the scrolled text but only appeared in the singing performances of the live broadcast. On November 11, 2008, they released an EP, Who's Gonna Save My Soul, featuring four versions of the song which originally appeared on The Odd Couple, along with a live version of "Neighbors" and a previously unreleased song, "Mystery Man." A music video for "Mystery Man" was directed by Walter Robot and premiered on Yahoo! Music.
