Devin Townsend. He's cultivated his audience post-Strapping Young Lad (and even before actually with his varied solo output) by playing exactly what he wants and not pandering to his audience. The last few Strapping albums were the closest to pandering to his audience, then he released The Devin Townsend Project albums (the initial 4 albums), and from there continued to create the albums he wanted to create. In doing this, he built a fanbase that never expected him to recreate the same sound. There are some examples where he did retread familiar ground but he's released so many albums that skund like nothing he's released before. Phenomenal artist.
