Life is about rhythm. We vibrate, our hearts are pumping blood, we are a rhythm machine, that's what we are.
There's nothing like music to relieve the soul and uplift it.
When the Grateful Dead needed a quality sound system to deliver our sonic payload, I learned electronics and speaker design.
Art in the classroom not only spurs creativity, it also inspires learning.
Dreams sometimes foretell the future.
