Led Zeppelin BBC Sessions album was released by Atlantic Records in 1997. It features some studio sessions and a live performance recorded for the British Broadcasting Corporation. The album was packaged as a double CD with disc 1 containing material recorded during three different BBC sessions in 1969 and disc 2 containing a concert performance at the Paris Theatre in London on April 1, 1971 (18 days prior to birth of yours truly, coincidentally).
Disc 2 has got the winners. These Led Zeppelin acoustic performances are magic AND they're played back to back.
