The London Jazz Archive is a collection of recordings made in the 1960s at various jazz clubs in London and now made available to listen for the first time. It includes performances by such as Sonny Rollins, Roland Kirk, Kenny Wheeler and Wes Montgomery. Many were recorded at Ronnie Scott’s so there’s plenty Stan Tracey on piano too who was the house pianist for musicians visiting from the US at the time.
