CA/CD was formed in Feb. 2010 as the alter-ego of Lehigh Valley based cover-band rockers, HeadKnocker. What started as a mini tribute set has evolved into a full-on tribute to one of the greatest rock bands of all time. CA/CD's long term goal is to become the Lehigh Valley's first nationally acclaimed tribute act. The band is comprised of 4 local, seasoned musicians with a combined experience of over 100 years in music. Two of CA/CD's members proudly walk among the elite group of "Pioneers" in the Lehigh Valley music scene, each with 25 plus years of playing with Valley based bands.
