Joseph “Muggsy” Spanier is mostly known as a hot lead trumpet player in small jazz groups and this is how he is presented on this double-CD. The majority of the material was recorded for World Broadcasting System between 1943 and 1952 and most of it has not been issued before.

Muggsy is in top form and his different groups feature important jazz stars like Pee Wee Russell, Eddie Condon, Darnell Howard and Barrett Deems. The discovery of some audio tapes made it possible to issue the recording sessions in full - master takes as well as alternate takes that were not previously issued on World Transcription Discs.

This release also includes an exciting jam session at the Sherman Hotel in Chicago 1941 with pianist Jess Stacy and drummer Baby Dodds.
