Laudate Dominum (Praise God) is another of Palestrina’s often-performed Renaissance motets. The wonderful five-voice imitative counterpoint makes it an ideal piece for brass quintet.
The sheet music is published by the TBQ Press - http://www.tbqpress.com/ Scroll down their listings to find the piece.
It is is also available as an unpublished brass sextet (link) available from me.
The mp3 performance is from my CD “Savannah River Brassworks,” available on my “recordings” page (link)
