Actually, Grissom represented a new type of jazz vocalist who came about more because of technological innovations than progressive musical thinking. Around 1933, microphones came into use, allowing singers such as Grissom or the Claude Hopkins frontman Orlando Robeson to carry on over the sound of a full band; neither man had the lungs to belt out lyrics over the top of the band the way pre-microphone "blues shouters" did. There was nothing loud about Grissom's singing style, described in a survey of Ellington vocalists as displaying "pinched-tones and heavy vibrato." Actually, he wasn't the only big-band singer in the Grissom lineage. His uncle Jimmy Grissom also sang with Lunceford, and was just about as busy on records as his nephew, with somewhat less negative critical feedback.
Dan Grissom joined the Lunceford band in 1935 and stayed on through the early '40s. The Sy Oliver arrangement of By the River Sainte Marie was supposedly Grissom's personal favorite amongst the stacks of songs he interpreted for Lunceford, though that might not mean it is any less gruesome. It was roughly a decade later that Grissom joined Ellington, staying through 1957, and among other accomplishments, recording a version of Ellington's tune Love (My Everything), also known as My Heart, My Mind, My Everything. Vocal wonder boy Johnny Mathis was reportedly influenced by Grissom from this period. Under his own name, Grissom pitied the Poor Butterfly in the mid-'40s with backing from the Flennoy Trio, a combo led by Lorenzo Flennoy on piano. Dan Grissom the Ebb Tones put out a single on Million in 1955 featuring the song Recess in Heaven, and there is also a rare Imperial single featuring Grissom's tribute to the King of Fools. ~ Eugene Chadbourne, Rovi
