Recently I made almost all of my pieces available at IMSLP (excluding the ones that are about to be premiered by whom it's dedicaded).
That's the page: http://imslp.org/wiki/Category:De_Faria,_Pedro_Henrique
Some of them are trombone solos, duos, or different combinations (bass trombone and cello for instance etc).
Maybe some of you will like them and want to perform it, or just hate it... don't know.
I'm just sharing the info since it's for free and could be useful/enjoyable for some people.
All the best.
