Bark at the Moon is the third studio album by British heavy metal vocalist Ozzy Osbourne, originally released on 15 November 1983. The album features former Mickey Ratt and Rough Cutt guitarist Jake E. Lee, who replaced guitarist Randy Rhoads who had been killed a year earlier in a plane crash. The album peaked at number 19 on the Billboard album chart and within several weeks of release was certified Gold for over 500,000 sales in the United States. To date, it has sold over 3,000,000 copies in the US In the UK, it was the third of four Osbourne albums to attain Silver certification (60,000 units sold) by the British Phonographic Industry, achieving this in January 1984. The album was remastered on CD in 1995 and again (with a different mix) in 2002.
Bark at the Moon is the only Ozzy Osbourne album on which the songwriting is credited entirely to Osbourne. However, he stated several years later in the liner notes to The Ozzman Cometh that the title track was in fact co-written by Jake E. Lee. Osbourne's bassist at the time, Bob Daisley, has stated that he co-wrote most of the music with Lee and wrote the vast majority of the lyrics. Due to legal issues, neither Lee nor Daisley's names were listed in the songwriting credits. Daisley has stated, however, that he accepted a buyout from Osbourne in exchange for writing credit. Osbourne's former drummer Lee Kerslake, who also played with Daisley in Uriah Heep after leaving Osbourne's band, stated that Daisley had been hired by Sharon Osbourne to write the Bark at the Moon album for "$50–60,000 or whatever it is. He was offered the chance to write with Ozzy. Words, music – write the album."
Some European pressings identified the track "Centre of Eternity" as "Forever". On tours for the album, Osbourne referred to it as "Forever". This can be heard on bootleg recordings of tours promoting the album. The title track was released as the album's first single with an accompanying music video. In the early 1980s infancy of the music video medium, the video, which was the first Osbourne had made, was highly anticipated due to his outrageous image. The decision to release "So Tired", a ballad, as the album's second single, was unpopular with many longtime fans. The track "Spiders in the Night" was originally only included on the European and Japanese releases, but was included on the 1995 CD reissue and the 2002 reissue, on which it was listed simply as "Spiders".
Composed by Daisley, the lyrics to the song "Now You See It (Now You Don't)" were a pointed rebuke aimed at Osbourne's wife and manager Sharon, who had fired him from the band in 1981. Daisley stated many years later that he was surprised the Osbourne camp allowed the lyrics on the album.
Shortly after Bark at the Moon's 1983 release, a Canadian man named James Jollimore murdered a woman and her two children after allegedly listening to the album. The timing was particularly inopportune for Osbourne, who was at the time facing allegations that his song "Suicide Solution" had influenced a fan to commit suicide.
Bark at the Moon is Osbourne's only studio album to feature drummer Tommy Aldridge, who was a fixture of Osbourne's live band for several years in the early to mid-1980s.
Bark at the Moon was re-issued again in 2002, although this version was actually a new remix of the album. This 2002 remixed version of the album was met with mixed reaction; many elements found in the original mix are not present in the remix, namely several lead guitar parts. In addition, the song "You're No Different" has an alternate ending (with the fade-out removed) and "Centre of Eternity" has an altered intro segment. This edition also included the bonus tracks "Spiders" and "One Up the 'B' Side".
