The legendary hardcore punk band Black Flag will reform for a one-off performance at Hevy Fest 2013, NME reports. Former singer Ron Reyes will front the 1979 lineup at the festival, which takes place Aug. 2-4 at the Port Lympne Wild Animal Park in Kent, England. It will be Black Flag's first U.K. concert in nearly 30 years.

Reyes, who heads to England alongside founding guitarist Greg Ginn, joined the band as a replacement for original singer Keith Morris. He left in 1980 and was replaced by fan Dez Cadenza. Henry Rollins famously joined in 1981 and stayed on board through 1986. He's since focused on his solo career, which has included spoken-word performances and stints as a TV show host.

"Celebrating our fifth year this summer, we have been working on some very special appearances for 2013 to mark the occasion," reads a post on the official website for Hevy Fest, and it looks like Black Flag is the first of those special appearances to be announced. More than 80 artists are expected to be added to the Hevy Fest lineup in the coming months.
