Overkill Biography (Wikipedia)
Overkill is an American thrash metal band, formed in 1980 in New Jersey. They have gone through many line-up changes, leaving singer Bobby "Blitz" Ellsworth and bassist D.D. Verni as the only constant members. Along with Anthrax, whose one-time lead guitarist Dan Spitz was also an early member of Overkill, the band is one of the most successful East Coast thrash metal bands, and they are often called "the Motörhead of thrash metal". The band has a notable mascot named "Chaly", a skeletal bat with a skull-like face, horns, bony wings and green eyes. Chaly has appeared on most of their album covers.
To date, Overkill has released seventeen studio albums, one album of cover songs, three EPs and three live albums. They were one of the early thrash metal bands to sign to a major label (Atlantic Records in 1986), but did not achieve commercial success until the popularization of the genre in the late 1980s, with their contemporaries Anthrax, Exodus, Metallica, Megadeth, Slayer and Testament. In terms of chart positions and sales, the band's most successful records are Under the Influence (1988), The Years of Decay (1989), I Hear Black (1993), The Electric Age (2012), and White Devil Armory (2014), which debuted at No. 142, No. 155, No. 122, No. 77, and No. 31 respectively on the Billboard 200 chart. As of 2006, Overkill has sold over 625,000 albums in the U.S. since the beginning of the SoundScan era, and over 16 million records worldwide as of 2012.
