Chalmers came to the attention of Bill Black, who called Chalmers for a session. Not long after working with Black, Willie Mitchell asked Chalmers to play on some of his recordings. Chalmers played lead sax on Mitchell's instrumental, "Soul Serenade". Mitchell then called Chalmers to work regularly on his productions, not only as a saxophone player, but also as an arranger and back up singer. Chalmers helped arrange and sang backup on "Let's Stay Together" by Al Green with a group that came to be called Rhodes, Chalmers, & Rhodes. They also sang on Green's album, "I Can't Stop", produced by Mitchell, for Blue Note Records, (2003).
