That's Nat is an album by jazz cornetist Nat Adderley first released on the Savoy label featuring performances by Adderley with Jerome Richardson, Hank Jones, Wendell Marshall, and Kenny Clarke.
The Allmusic review by Ron Wynn states "His pithy, pungent trumpet and cornet work is effective in a hard bop context, although his own work outside his brother's group has never seemed quite as effective".
