The sound leakage from my basement is okay in terms of not disturbing
neighbors "too much," but I'd still like to reduce it further so that I can
record later into the evening.
Most of the sound seems to escape from window locations. I'm talking
mainly about bass drum and toms, but also my guitar amp.

I know you need mass to reduce sound. If I cover the windows and interior
walls with, say, 8'x4', 1" sheets of high density fiberboard (compressed
sawdust), will I get any appreciable reduction of sound through the
windows/walls? There will be gaps above the boards (10 ft. ceiling) and the
entirety of each wall will not be covered. Perhaps 70% of the walls can be
covered with the fiberboard sheets. Would there be a better choice than the
fiberboard? Heavy fiberglass sheets, perhaps?
Thanks!

I had the same problem with windows, and I built "plugs" out of 2"
Johns Manville I/S 600 (equivalent to 703) and luan board. I covered
it with basic cotton cloth from Walmart, and stick the luan towards
the window, with the insulation towards the room. I also have
shutters I can close over that to really tighten things up.
