Adrian Paul Erlandsson is a Swedish heavy metal drummer who is a member of At the Gates, the Haunted, and Nemhain (2006–present).

At the Gates is a Swedish death metal band from Gothenburg, formed in 1990. The band was a major progenitor of Gothenburg-style melodic death metal alongside In Flames and Dark Tranquillity. Prior to their first disbandment in 1996, At the Gates released four albums, ending with and including Slaughter of the Soul (1995), which has been seen as a landmark in the mid-1990s Swedish death metal scene as well as being a major inspiration for many metalcore bands. After reuniting for a one-off tour in 2008, the band reformed once again in 2011, and they have since released three more albums: At War with Reality (2014), To Drink from the Night Itself (2018) and The Nightmare of Being (2021).
