I feel all religions are aiming at the same G-d (see clip above), and that a place of prayer is not a place to entertain, which as a musician, in the broader sense is what I also do. And so I refrain from performing in any room dedicated to prayer.
But an annexed hall in the building is fine.
I also only perform on a real piano, along with the below small, but mutually beneficial criterion list:
A real piano in a non designated prayer room,
(not a keyboard - even hidden inside a real piano case, which I sometimes find).
A minimum one hour set up time allowed
Allowed as required to move the piano so the right hand side (curve side) faces towards the audience.
re Covid; a safe distance can be maintained or a screen put up as required, but I am not able to perform wearing a mask.
I can not perform while people eat.
NON ESSENTIALS but preferable:
Doors open to performance area at least a half an hour prior to performance start time
A seated venue
Show time basically to be 45 mins, likely to run for an hour, with an allowance for a further extra half hour run on maximum
An in tune piano for best results, with all notes working
No hidden / out of sight corners in the room.
If an area in the room has no line of sight to the performance area, if possible it should be closed off.
Thank you for your understanding and patience,
looking forwards to a very special event for all.
