It serves as the follow-up to Mars's debut record Doo-Wops & Hooligans (2010).

It was released on October 4, 2010, by Atlantic and Elektra Records and was made available to listen before its official release on September 24, 2010.

The album title was chosen to reflect simplicity and appeal to males and females.

Soundgarden was an American rock band formed in Seattle, Washington, in 1984 by singer and drummer Chris Cornell, lead guitarist Kim Thayil (both of whom are the only members to appear in every incarnation of the band), and bassist Hiro Yamamoto; Cornell switched to rhythm guitar in 1985, replaced on drums initially by Scott Sundquist, and later by Matt Cameron in 1986. Yamamoto left in 1990 and was replaced initially by Jason Everman and shortly thereafter by Ben Shepherd. The band dissolved in 1997 and re-formed in 2010. Following Cornell's death in 2017 and a year of uncertainty regarding the band's future, Thayil declared in October 2018 that Soundgarden had disbanded once again, though they did reunite in January 2019 for a one-off concert in tribute to Cornell.

Beth Nielsen Chapman has long been a music-industry favorite. To say she’s had it rough, though, barely does justice to the events that inform 1997’s Sand and Water and its follow-up, Deeper Still—the death of her husband and her subsequent fight with breast cancer. Deeper Still‘s acceptance of hard truths resonate with listeners.

A project of William Orbit, the band included vocalist Sharon Musgrave and rapper MC Inna Onestep amongst others. For the second album, singer Sindy Finn replaced Sharon Musgrave on vocals.

Strange Highways is the sixth studio album by American heavy metal band Dio. It's also their first album since Ronnie James Dio and Vinny Appice's reunion tour with Black Sabbath. The European release was on Vertigo, in October 1993; the U.S. release was on Reprise Records, in January 1994.
After the short-lived reunion with Black Sabbath for the recording of the album Dehumanizer (1992) and the subsequent tour, Dio and Appice returned to Dio's solo group, hiring Tracy Grijalva as new guitarist. Former Dio bassist Jimmy Bain was to make a return to the band, but he was soon sacked by Dio and replaced by Jeff Pilson. It is considered Dio's heaviest and darkest album.

Magica is the eighth studio album by American heavy metal band Dio. A concept album, it was produced by frontman Ronnie James Dio and released on March 21, 2000, through Spitfire Records.
The album marks the return of guitarist Craig Goldy, who also has performed on Dio's album Dream Evil and in the later release Master of the Moon. Magica also features Jimmy Bain on bass and Simon Wright on drums. The album was originally planned to be the first part of a trilogy of concept albums. Shortly before beginning his tour with Heaven & Hell, Dio announced his intention to start the Magica II & III album after the tour's end, but he died shortly after of stomach cancer on May 16, 2010. The only song released from Magica II & III was titled "Electra".

Lock Up the Wolves is the fifth studio album by American heavy metal band Dio, released on May 15, 1990. It displayed a complete change of musician line-up over the previous Dream Evil album, including 18-year-old guitarist Rowan Robertson, and Simon Wright on drums who had played with AC/DC from 1983 to 1989. The song "Evil on Queen Street" takes its title from a deli in Toronto which had a sandwich with that name—per Dio on Much Music in 1990.

Dream Evil is the fourth studio album released by the American heavy metal band Dio, on July 21, 1987.

It was also the last album to feature bassist Jimmy Bain until the release of 2000's Magica.
