Here I am in sunny Rockford with the great Phillip W. Serna. Phillip is an excellent bass player and a great guy. He runs a double bass studio in the Naperville, IL area and plays a lot of early music on violone and viola da gamba as well as more traditional repertoire on the double bass. Check out his website here. He and I both went to Northwestern together and played in the Civic Orchestra of Chicago together. Phillip also has an extension made by Chris Threlkeld-Wiegand.
