Ony of my all time gospel favorites is "Spirituals & Gospel: Dedicated to Mahalia Jackson" by Mavis Staples and Lucky Peterson. Glorious Hammond B3 on every other track, vocals that send a child down your spine and, icing on the cake, excellent sonics.
Another interesting recent choice is "Gotta Serve Somebody: Gospel Songs Bob Dylan", an album of often undeservedly underrated Dylan songs from his Christian period, performed by the likes of Shirley Caesar, Sounds of Blackness and Aaron Neville.
Unfortunately, a lot of what is currently being marketed as gospel sounds much like formula soul except for the lyrics. I guess that's why I still listen to lots of Mahalia.
