for pure sound quality combined with performance magic the two that stand out to me are the 45rpm Classic Records reissue box sets of "Belefonte live at Carnigie Hall" and "the Weavers, 1963 Reunion". these are not rock and roll but will simply grab you and pull you completely into the performances.....almost unreal. if you are looking for the perfect recordings these just may be it.
next best would be my mint Nautilus half-speed of "The Allman Brothers, Live At The Filmore East".......totally great music but not at the magical sound quality of the other 2.
