Jazz At The Pawnshop is the first one that popped into my head.
Fantastic! if you like this style.
Feels like you are actually at a small jazz club for the evening.
"Since its recording in 1976 this has been a bit of a cult classic, renowned for clarity and quality as well as for the fact it presented some of the most intelligent, relaxed and truly musical mainstream ensemble jazz since the genre was invented!" - Jurgen Gothe, CBC Radio Guide.
