Olof Gustafsson (also known as Blaizer / The Silents) is a Swedish video game music composer. He started doing music for a demogroup called The Silents. Several members of this group decided to go into game development, and started Digital Illusions. Gustafsson joined them, and did the music for most of their early games. In 2005, he left Digital Illusions to start a new company, called Motherlode Studios, later known as Epos Game Studios AB. He has also contributed tracks to the Merregnon CDs.
In 2003, the demoscene saw a surprise return of Blaizer in the TBL demo Magia. He has continued to provide music for TBL demos ever since.
