From Scott Goodwin -

The SOURCES_SG mixes are just a collection of mixes I've been doing to
articulate some ideas for new Operative material. Plus its just fun
to share these things and have it be a cool, curatorial thing. The
first one was focused on, sort of, different "experimental" tangents
in dance music and vice versa, different explorations of "dance music"
by people with more avant-garde or multi-disciplinary backgrounds.
It's still up for d/l at operativegroup.org. This one focuses mainly
on expansive timbres with a focus on composers like James Tenney and
Maryanne Amacher, as well as a few selections from the '03-06
"Collective JYRK and affiliate" archives, mixed with some more gonzo
stuff like Matt Carlson's ur-acid house from his recent "difficult to
listen to" Gift Tape and Rovo's the post-Boredoms take on fusion.
