For me its the first or very early LP's of: Allman Brothers - "Allman Joys" "Idyllwild South" Santana - "Santana" 200 g reissue Emerson Lake and Palmer - "Emerson Lake and Palmer" and, Beethoven - "Piano Concerto No. 4 in G Major" Rudolph Serkin/Ozawa/BSO
I think my initial description was spot on. Sounds similar to Santana with a funk/soul groove. The SQ is all analog, dynamic, punchy, extended. I haven't tried, maybe some YouTube videos are out there.
