Michael Brecker & Bob Mintzer - Twin Tenors
Dave O'Higgins - Sketchbook (with Eric Alexander)
Eric Alexander & Lin Halliday - Stablemates
Reeds & Deeds (Eric Alexander & Grant Stewart) - actually have 3 albums. Wailin', Cookin', and Tenor Time.
Tenor Triangle (Eric Alexander, Ralph Lalama, & Tad Shull) - two albums. Aztec Blues & Tell it Like it Is.
And while not a complete album, listening to Coltrane & Sonny Rollins both play on the title track to Rollins' Tenor Madness is just amazing.
