In 1988, the group Chapter Seven won a Grammy for the album Thums Up, and when Caprice reissued the album on vinyl last fall, the group got together and did a release concert that was so successful that the gang decided to play a few more times. Therefore, the group will gather this September, perhaps for the only time, for a few concerts in connection with the simultaneous release of an album from their appearance at the jazz festival in Chicago in 1990.
