Churchill Grounds was the epicenter of the Atlanta jazz community for many years. Proprietor Sam Yi supported the jazz community and provided opportunities for both experienced musicians, and those just starting their careers, to perform at his club. Bassist Dishan Harper was a bright light in the jazz community. His relationship with Churchill Grounds goes back to when his father, Danny Harper, started hosting his legendary jazz jam session in 2000 and it’s where Dishan began his training as a jazz musician. The jam session at Park Tavern brings together some of Atlanta’s - and the world’s - finest musicians to honor these beloved members of the community and the legacy of Churchill Grounds.

Musicians joining Lil John Roberts and Russell Gunn for the jam session include Kevin Bales, Kenny Banks, Kenton Bostick, Phil Davis, Julie Dexter, Joe Gransden, Terreon Gulley, Terence Harper, Louis Heriveaux, Mace Hibbard, Frank Houston, Che Marshall, Gary Motley, Joel Powell, Tia Rix, David Sanchez, Derek Scott, Craig Shaw, Kevin Smith, Mike Walton, Nathanael Fareed Williams, and Larry Wilson.
