Louis Armstrong and his Hot Seven was a jazz studio group organized to make a series of recordings for Okeh Records in Chicago, Illinois, in May 1927. Some of the personnel also recorded with Louis Armstrong and his Hot Five, including Johnny Dodds (clarinet), Lil Armstrong (piano), and Johnny St. Cyr (banjo and guitar). These musicians were augmented by Johnny Dodds's brother, Baby Dodds (drums), Pete Briggs (tuba), and John Thomas (trombone, replacing Armstrong's usual trombonist Kid Ory, then touring with King Oliver). Briggs and Thomas were at the time working with Armstrong's performing group, the Sunset Stompers.
