Metallica was a musical guest at BlizzCon, the first virtual version of Blizzard’s games convention, and performed its classic song “For Whom The Bell Tolls” live from its Northern California headquarters in San Rafael. In a weird move, BlizzCon replaced Metallica at the end of BlizzConline’s opening ceremony with generic royalty-free music to avoid a DMCA takedown. The band’s appearance was introduced by an onscreen message noting that “The upcoming musical performance is subject to copyright protection by the applicable copyright holder.” Twitch needs to get this together in the future.
