Urbie Green was a sideman on many small group recordings. Here are some I found on my shelves.
Gil Melle - The Complete Blue Note Fifties Sessions
Buck Clayton Jam Sessions - Mosaic
Benny Goodman Septets and Octets - Music Masters
Joe Newman - RCA
Session At Riverside - Dormouse
Med Flory Orchestra 1954-1959 Go West Young Med! - Fresh Sound
Elliot Lawrence - Jazz Goes Broadway - RCA
Frank Wess Sextet - Commodore
Another fine Danish tenor player is Bernt Rosengren.
Swedish born Tomas Franck lives in Denmark as does American born Bob Rockwell. Both very good tenor players.
Yes that is the one. Not sure where you found the image? I looked in about 7 or 8 places online without success.
However, the bottom line is that this is an outstanding CD.
Beethoven String Quartets - Op.18/1, Op.18/2 Op.18/3 - Smetana Quartet - Denon
Searched extensively, but was not able to find an image of this CD.
It is a marvelous CD with perhaps my favorite versions of these Beethoven quartets.
