That's really hard. It can depend on my mood/the day as to which songs appeal to me the most. I do like to hear the improvisations in the live versions of No Quarter. I like hearing piano & drums work closely, supplementing, accenting, leading, etc. I like to hear the various combinations of medlies they used for 'whole lotta..' I like to hear the very early 'b blues' influence on the band during their live work. More evident around '68-70. But sometimes I like to just settle for their studio feats.

In particular b blues I'm refering to the harmonica improvisations in You Shook Me, Bring It on Home, & other covers, etc. You shook me '69 live is considerably different to later yrs, & was different b/w each performance for that matter (BBC Sessions live) is another example which is more keyboard based than harmonica. And I have a recording of YSM a day after another which is guitar based (all '69 versions.) All these versions quite different/ less b blues accented than the '72 HTWestWWon. 'Hats off to Roy Harper' from LD3 sums the bblues influence up.
