Sylvia started in the San Francisco alt-punk scene in the eighties fronting her own all-girl band “Revolver”. Their self-produced demos caused a stir in the underground scene. So much so, that other bands asked for Sylvia’s help in the studio. This led to her working with a number of notable bands.

She has worked as studio engineer at Larrabee Sound Studios and [l269124]. Starting in 2001, she owned and operated RadioStar Studios out of the [l627202] until its closing in 2012.

[l490688] is her current own studio.
