ESP recordings: where were they recorded?

[Pim]

Ive noticed that studios are seldomly if not never mentioned. It always says: recorded in NYC. Did ESP Disk use the same studios for recording or is there anything known where those sessions took place?

Judson Hall, I believe

I seem to remember but I may be wrong that there is a photo of Brownie at an esp-disk session at Judson Hall

Many were recorded at Richard Alderson’s RLA Studios,
