east wall done
did the rest of the framing for the wall between the studio and garage today:

you may be wondering about the unframed space to the right. that's intentional -- the wall that meets up at that corner will be splayed. that will also leave plenty of space with which to do any funky ductwork turnaround stuff that might have to be done for sound isolation purposes.
you might also be wondering about that 2x6 on the left. that's not really too common in standard corner framing--usually you just use a 2x4--but for studio stuff where there are 2 or 3 layers of drywall applied in staggered fashion, this extra width is needed in order to make sure the edges of all the drywall layers will have something to screw into.
it's a little tough from that photo to differentiate between the studio-side frame and the garage-side frame, so here's a closeup of the base of the frames to give a better view of the space being left in between for the air cavity:
