Looking for Blues with High Fidelity

"Come On Home" by Boz Scaggs is more bluesy R&B than Blues but it's a terrific sounding disc and the playing/singing is excellent. 

I have most of Doug MacLeod’s work.
It seems to be generally very well recorded.

This may be of interest. It looks like these remaster are to be released this month.
