Narrative:

Approach control cleared us to switch to tower, fast decelerating visual. Captain's radio failed during landing phase. Landed without clearance. After radio #2 tuned, contacted ground, no problems. Captain was not flying and should have realized no landing clearance given, but got busy. Radio failing in close, no help.
