I just want to point out that a directional (cardioid) bonduary mic (the
PCC160 is not actually a PZM) can be more effective than a semi-omni (half
sphere).
For on-the-street buskers I'd place the microphones on the curb right in
front of the players... something closer to an XY or maybe you can
experiment with an AB too....

You are speaking here of boundary mikes?
