The Schagerl Brass Festival: Monday YouTube Fix
Andrew Hitz
I stumbled onto this video which is not in English and doesn't list the players or what they are playing but it features a number of members of Mnozil Brass, Gábor Tarkövi (Principal Trumpet - Berlin Philharmonic), and many others!
It is a long video with some of the finest brass playing you will ever hear. It opens with a performance of Copland's "Fanfare for the Common Man" that will blow you away.
Enjoy!
