Cool in Rhythmn (dedicated to Stan Kenton) is played by Theo Jörgensmann, basset clarinet; recorded live in Hamburg, Germany. Converted to ogg by Herbert Weisrock
This sound is very simple and was made by anhembi morumbi university's students on studio. You can use it for opening sounds in general, but it suits like 100% a champagne opening (in my opinion) and the one who recorded it was maria laura ligeiro cavalcanti.
