Portnoy may be my biggest influence in the overall approach to the drumset, but it was Ray Herrera who has influenced my double bass playing the most. As soon as I heard the Fear Factory album "Obsolete," I was hooked on his playing. His ability on the bass drums always keeps me listening. The way he plays double bass utilizing patterns is what really got my attention. This has definetely been one of his biggest effects on my double bass playing. Patterns are what I prefer playing, as opposed to straight ahead beats at fast speeds (although he handles those with ease).
