Absolutely! You could put a Parlour Gig in a cupboard if you wanted!
(We wouldn't actually recommend putting anyone in a cupboard...)
We encourage everyone, with any sized space to host a Parlour Gig.
They can take place in your backyard, balcony, kitchen, or bedroom; anywhere you can fit a musician and a bunch of friends!
The only thing to keep in mind is that some artists have a minimum capacity.
