Exodus – The Battle of ’24

Gary Wayne Holt (born May 4, 1964) is an American guitarist from the San Francisco Bay Area. He is a guitarist, the bandleader, and the main songwriter for the American thrash metal band Exodus and is also a guitarist for the American thrash metal band Slayer, in which he took over duties for original guitarist Jeff Hanneman, who died in 2013. After guitarist Tim Agnello left Exodus in 1981, Holt joined the band and has been the main songwriter and the most senior member of the group ever since. Following Kirk Hammett's 1983 departure from Exodus to join Metallica, Holt kept the band going and for many years, he and Rick Hunolt were referred to as the Exodus' "H-Team" guitar players. Holt is the only member of Exodus who has played on every album.
