Here is a clip from the 2014 Eastern Trombone Workshop featuring an all-star low brass section playing through a number of orchestral excerpts. The lineup:
Toby Oft - Principal Trombone, Boston Symphony
Nathan Zgonc - 2nd Trombone, Atlanta Symphony
Jeremy Wilson - Former 2nd Trombone, Vienna Philarmonic & Vienna State Opera
Stephen Dunkel - Bass Trombone, Washington National Opera
Seth Cook - Principal Tuba, Charlottesville Symphony
They play orchestral standards from Bartok, Tchaikovsky, Mahler, Hindemith and many more. This is an example of great players who are not a regular section molding each of their strong personalities into one cohesive idea. There are some great insights into playing in orchestras as well as things like auditioning from each of them.
