As part of the ongoing celebration of their 20th anniversary, Swedish progressive metallers OPETH will release live footage and audio from the band's recent performance at London's famed Royal Albert Hall. "In Live Concert at the Royal Albert Hall", due on September 21 via Roadrunner Records, is a fierce testament to OPETH's continued success in the progressive metal community.

Twenty years and nine records into their legendary career, OPETH's "progressively creative spirit" (ARTISTdirect) remains unwavering, propelling the band through the "Evolution XX: An Opeth Anthology" tour, which brought the Swedish titans to six of the world's most unique venues, and now, with the release of "In Live Concert At The Royal Albert Hall", into the homes of their fans.

The performance at the Royal Albert Hall (recorded on April 5, 2010) includes two sets, the first consisting of the band performing 2000's now-classic, breakthrough epic "Blackwater Park" in its entirety, and the second, a chronologically arranged selection of material from the rest of OPETH's extensive catalogue, totalling almost three hours of music. It is, like the rest of OPETH's greatest work, "purposefully warped in all the right places" (Decibel). The front cover artwork concept pays tribute to DEEP PURPLE's "Concerto for Group and Orchestra", underlining the band's longstanding love for their prog-rock roots.
