I have a new arrangement up for beatboxing flute quartet. It's Metallica's "Enter Sandman"! You can listen to a live recording and buy the sheet music here: https://nikkinotes.com/EnterSandman.html
This is part of Sheet Music Plus' 2017 Chamber Music Contest, the person with most sales the net 2 months wins! So if you are thinking about buying for an upcoming concert, go ahead and take the plunge and get it. It would help me out!
