From birth, Alexander Claffy was raised in a musical household (his father is a pianist, his mother, a vocalist), and had many of his earliest lessons on bandstands in the heart of Philadelphia. As a teenager, Claffy was fortunate enough to find a mentor in many Philly natives, and has continued his study of the double bass with some of the world's finest musicians, including Ron Carter, Dwayne Burno and Orin O'Brien. Since moving to New York City in 2011, he has had the honor of working with many of his living heroes, including Jimmy Cobb, Louis Hayes, Harold Mabern, Kurt Rosenwinkel, Christian Scott, Joey Alexander, Wallace Roney and many more.
