Buster Baer - Guitar, Bass, Drums, Uke Class

Buster first picked up music at 17 as an addition to his love of poetry. However, what started as a side dish quickly became the main course as his whole life began revolving around music. Over the years Buster has played in many bands, gigging regularly in New York City, New Orleans, San Francisco, and Los Angeles. Buster has written literally thousands of songs, and produced over 150 recordings.

Now Buster mostly focuses on recordings and teaching, his students ranging from complete beginners to professionals with more technical skill than he has. What keeps the students coming back is Buster’s patience, direction, and commitment to creativity. Most lesson plans will treat creativity as a talent you are either born with or born without. Buster couldn’t disagree more. Creativity is a human muscle and it exists in all of us equally, whether atrophied or not.

Come practice your creative health and develop a challenging and impressive skill to communicate and express yourself with sound!
