SeriousMF (aka Serious M*ther F*cker; beartowitness) is a Producer who started using YouTube and VOCALOID to showcase his original music. His primary VOCALOID is SONiKA, although he makes songs with Sweet ANN and Tonio as well. Many of his works contain themes such as a mechanical being that is infatuated with humans and clever lyrics using technology terms. However, he is not strictly a VOCALOID producer, as he writes, sings, and produces a number of his own original music without the program.
STATUS:February 2010 → Partially Retired from Vocaloid production
