1971 Reverber/ ation (Boxed Set, With DVD, With Blu-ray, Digipack Packaging)Description Three disc (CD + DVD + Blu ray) set. In 1971 Pink Floyd recorded the Meddle album, containing the LP side long 'Echoes', regarded by many as laying the groundwork for The Dark Side Of The Moon, and, as such, is an important part of The Pink Floyd canon. This package includes part of the original demos, when the project gestated from Nothing to Return Of The Son Of Nothing, as well as a contemporary BBC session recording. Audio visual
