The Essential Ozzy Osbourne is a compilation album by British heavy metal singer Ozzy Osbourne, released in 2003. It reached No. 7 on US charts and No. 21 in the UK. Tracks featured here from the first two albums are the re-recorded versions from recent reissues as well as the remixed Bark at the Moon tracks. The album was certified Gold by the RIAA on 5 February 2005 with an excess of 500,000 copies sold, then certified Platinum by the RIAA on 3 March 2016. This compilation was re-released in 2009 as a Limited Edition 3.0 package with an additional disc of bonus songs that were not on the original release. The album tracks from Blizzard of Ozz and Diary of a Madman are from the 2002 remasters, for which they were partially re-recorded. The original drum and bass tracks were replaced with recordings by Osbourne's then-current bassist Robert Trujillo and drummer Mike Bordin, as a management response to legal action by original bassist Bob Daisley and drummer Lee Kerslake for unpaid royalty fees. It does not feature any material from 1986's The Ultimate Sin; however, the limited edition bonus disc does include two tracks from it.
