Adrian Paul Erlandsson (born 27 October 1970) is a Swedish heavy metal drummer who is a member of At the Gates (1990–1996, 2007–2008, 2010–present), the Haunted (1996–1999, 2013–present), and Nemhain (2006–present).

"[citation needed] They also started playing with their music teacher at school, and eventually began to write their own songs and formed a band.

The first song they learned was Joan Jett's "I Love Rock 'n' Roll" They soon gathered more members and began playing covers by bands like Def Leppard, Dokken, The Exploited, GBH, Thin Lizzy and Twisted Sister.

When asked what each at the Gates member contributes to the group's overall sound, bandmember Anders Björler said that Erlandsson "hit the drums hard".

2 weeks into June I was asked to join Cradle of Filth in England, mainly to help them out with some session recording and a few gigs… Since it worked so well… I ended up joining the band on a permanent basis…In 2006, according to an official Roadrunner press release, Erlandsson left with the intention of devoting his energies to his two side projects, Nemhain and the since-defunct Needleye.

Nemhain recorded its debut album From the Ashes in Studio Fredman during the late spring 2008 due for a release in April 2009.

In March 2009, Erlandsson joined the British gothic metal band Paradise Lost under Jeff Walker's recommendation.

In June 2016, he announced on his Facebook page that he will no longer play drums for Paradise Lost due to other band commitments.

While Adrian was in Cradle of Filth, due to band's poor reputation in the black metal scene, he was fired from Nifelheim, who said it was "like a very bad, bad dream" to have had "a drummer who plays in CRADLE OF WIMPS now", and that he was "a schooled drummer" but "had problems to understand the most twisted and sickest riffs".
