Great list!!!!!
I'll add EARLY Lou Rawls. Check out his album with Les McCann and Les's trio. I just lent a copy to a new 'phile friend I met here on the 'Gon. He reluctantly borrowed it and told me when I visited him and his rig that it is amazing.
Please please do yourself a favor and listen to Lou Rawls & Les McCann Stormy Monday. The album is amazing. Listen to how well it's recorded. Listen to how Lou (I think he's in his 20s) handles these standards and develops them with great vibrato and that amazing Lou deep tone. He has such moxy in spots. Such attitude. Give Outskirts of Town a roll.
