The release of Pink Floyd [ tickets ]'s two-CD live "Wall" album will be delayed until Feb. 7, 2000 because of the time-consuming process of preparing the music from the original tapes.

EMI Music said the tapes had been in storage and have never been treated or mixed since they were recorded at concerts in London, New York, Los Angeles and Dortmund, Germany in 1980-81. ''The technical processes involved in restoring and mixing these old tapes are very complex and thus the work currently being undertaken by producer James Guthrie is very delicate and has taken longer than expected,'' the label said in a press release.

Separate from EMI's release of the live ''Wall'' album, Sony/Columbia will release the popular movie ''The Wall'' on DVD. The release date for the film was pushed ahead from Dec. 7 to Dec. 14 late last week.

The DVD release includes a 25-minute documentary about how the film was made and a 45-minute documentary of interviews with former Floyd leader Roger Waters [ tickets ], animator/co-director Gerald Scarfe, co-director Alan Parker, music producer Guthrie and film producer Alan Marshall. The music accompanying the film was remastered from the original tapes, according to Sony/Columbia.

Waters is expected to release his French/English opera ''Ca Ira'' next year, though Columbia hasn't set an exact date. Waters has been working on the project for some seven years, taking a break earlier this year to tour the eastern U.S. He will probably undertake a complete U.S. tour next spring or summer, said his booking agency. Unlike the '99 tour, West Coast cities will be on the roster.
