Yes.  You can play music on both frontends simultaneously.
No.  There is no mechanism to maintain synchronization of playback for 
two independent frontends.

You either need to have a single, central playback device, with audio 
lines run to both amps, or you will need to develop some synchronization 
mechanism to keep playback of both frontends in lock-step.  Note, the 
ear is very good at picking out delayed audio.  For a muted echo, 
anything within a few dozen ms would likely be sufficient.  If both 
sources are at the same perceived volume, more than a couple ms will be bad.

The brain doesn't like when an echo is too loud.  It's competing range 
cues, and you can't unconsciously ignore it.  It's the same reason why 
stereoscopic TV, with variable convergence but static focus, gives many 
people headaches.
