Augustin Gonzalez Acilu - but I will also admit I was pleasantly surprised and it goes really nicely between the Martinu Trio #2 and the Reger Quintett.

As always, the concert is broken up into two parts - Part one (top player) has the Martinu and Acilu and Part two (bottom player) has the Reger.

Here are the notes:
