Lot of great lists here, will have to look carefully myself.
Echo ridiculously cheap hybrid sacds from acoustic sounds which I did grab.
Have not listened yet to check sound quality, but good songs on them.
Guessing they overbought, but can check out songs at Tidal, Spotify, etc
before buying.
Like people said Muddy Waters Folk Singer in the room sound quality.
Have Mobile Fidelity but people have stated SACD even little better.
(3 performers recorded at different times, incredible magic of mixing/mastering)
Jimmy Hendrix Blues also saw on list, essentially in the room sound.
A compilation album.
Not mentioned, good, not great sound quality-acclaimed Clapton Unplugged
Another in the room sound is harder blues out of Madison, WI
Paul Black and the Flip Kings, King Dollar, great album
Great album, good sound quality is acclaimed BB King Live at the Regal.
Eva Cassidy Live at Blues Alley, very good sound quality, mix of different types of songs including the blues, jazz, ballads, etc. Sound can be little edgy.
Versatile singer. Became famous after death from aggessive cancer.
Also agree with Doug McLeod and Keb Mo, though have not listened in a while.
But recall basically in the room sound quality.
Albert Collins Cold Snap, MFSL also very clean, think was listed here.
