A memorial for Slayer's Jeff Hanneman, who died earlier this month at age 49, is set for May 23 at Los Angeles' Hollywood Palladium. The memorial, which will be open to the public, is set to last four hours, from 3:30-7:30 p.m.

Attendance of the event, which is all ages, will be on a first-come, first-served basis, subject to venue capacity, which is listed at around 4,000 people.

Hanneman died May 2 of liver failure, with the official cause of death named as alcohol-related cirrhosis a week later. His death comes on the heels of his 2011 bout with necrotizing fasciitis, commonly known as flesh-eating disease, which Hanneman claimed to have contracted from a spider bite in a hot tub.

Hanneman, the metal act's longtime guitarist, co-founded Slayer in 1981 with fellow guitarist Kerry King, bassist Tom Araya and drummer Dave Lombardo. The band went on to release 11 studio albums during Hanneman's tenure with the band, most recently 2009's "World Painted Blood," which hit No. 12 on the Billboard 200. One of the band's quieter members, Hanneman often stayed out of the spotlight despite his major influence within the band as one of its principal songwriters.

News of the memorial follows a post made to the band's Facebook on May 9 revealing that a public celebration of Hanneman's life was in the works.
