We call it Musikong Bumbong which means musicians with bamboo cylinders. The band is like an ordinary marching band except that the instruments are all made of bamboo, the wind and the percussion. I had witnessed the performance of this marching bamboo band once when I was still young (sadly no digital camera yet) and I was mesmerized because it is amusing to hear the sound of those bamboo intruments. From what I know, the bamboo band is still performing in the province of Bulacan during summer time.
