Not into vocals much,but yeah,Allison Krauss Live album is excellent.Then soundstaging/imaging,it's a tossup between Ray Brown Live at Scullers and probably David Hazeltine Classic Trio.For bass,that's more dificult, but the title cut on the Junior Mance Blue Mance album is a boogie/bass treat,thanks to Keter Betts' bass mastery.Some may find this surprising but also for bass the remastered Herb Alpert South of the Border album sounds amazingly good all round,and the bass is superb.
