Spencer has been creating art and music since he was a young boy. For most of his adult life he was in the music business, recording and producing hundreds of records while working as a technician on over 20,000 pianos, crank phonographs and pump organs. Collecting and working on pianos, he eventually found himself creating assemblage art before he knew what it was called. When the music industry collapsed in 2008, he shifted his focus to assemblage art full time.
Brewer and Esther Siegel are the co-authors of Lost and Found: Assemblage Artists of Northern California. A portion of proceeds from the book will be used to help internationally-acclaimed assemblage artist Larry Fuente, who lost his 8,000-square-foot warehouse of finished pieces and art supplies to a devastating California wildfire.
