The release of Pink Floyd's live version of their 1979 concept album The Wall, originally scheduled for Dec. 1, will be delayed until Feb. 7, according to EMI Records. The album's producer needs additional time to mix and restore the concert tapes from 1980 and 1981 that will make up the LP, the record company said. The two-CD set will be called Is There Anybody Out There? — The Wall Live. The Wall, which spawned the hit single "Another Brick in the Wall Part II" and spent 15 weeks at #1 on the Billboard albums chart in 1980, was largely the work of Floyd bassist Roger Waters, who left the band in 1984.
