LED ZEPPELIN / HEAVY METAL Maryland Monitor Mix (5CD)

The first appearance master that was kept with the soundboard master of that amazing 1975 Minneapolis performance, the monitor mix soundboard on the second day of the 1977 Maryland continuous performance.
It is clearly different from the sound board that has already been released, and it is exciting because Bonzo’s drumming stands out more.
Unfortunately, there are parts where the storage condition of the tape is not good, so there are cuts and not all songs are recorded.
Therefore, we have included the SBD x AUD Matrix on 3CD as a bonus.
