Some Kopprash and some Arban!
First of all another mp3 in the "Art of Phrasing" section: N. 148 (Blue Bells of Scotland), if you can buy Lindberg's version of this piece (he is a PHENOMENAL trombone player!!!)

Then 2 new Duets from Arban: 10-11, easy ones but always "educational"!!!

Then to Kopprasch: N. 5, 9 and 10.

Now I'm going to record something else!

Have fun!
