I was planning to build a soundproof wall in the house against a load-bearing concrete wall. Do I need to board the "back" of the steel stud as well for it to be stable?
Cross-section diagram of a soundproof wall with layers: concrete wall, air gap, 45mm steel frame with insulation, and OSB + gypsum panels.

No, but maybe an angle that is attached to the concrete wall in the middle of the steel studs + staggered joints on the boards.

Exactly what I was considering, to attach a bracket to the wall.
Yes, the panels will overlap at the joints.
