As part of the celebration of their 20th anniversary, Sweden's Opeth released a DVD of the band's performance at London's Royal Albert Hall. 'In Live Concert at the Royal Albert Hall' is a fierce testament to Opeth's continued success in the progressive metal community. Opeth performed two sets that evening - the first, a performance of the classic 'Blackwater Park' in its entirety, and the second, a chronologically arranged selection of material from the rest of Opeth's catalogue..
