Drummer Austin McMahon completed his Bachelors and Masters of Music Degrees in the University of Miami's Studio Music and Jazz program. Austin was a member of U.M.'s acclaimed Concert Jazz Band for two years and was a member of many original bands based out of South Florida including the Music Lover's Club, a group which performed at Carnegie Hall in March 2004.

Austin has performed with the New York Voices, Joe Lovano, Curtis Lundy, Bob Mintzer, David Liebman, Jim McNeely, James Moody, and Ira Sullivan among others. He has traveled throughout the East Coast of the U.S.A, the Caribbean, Germany, Switzerland, Finland and Spain performing jazz and original music. Austin currently resides in Boston, MA and divides his time between teaching, playing, composing, and loving music.

When Austin composes for the Quartet of Happiness, he likes to convey an image to the audience therefore his compositions contain elements of improvisational comedy (skits) as well as being vehicles for the group to push their limits on their instruments.
