I'm co-hosting open mic/stage events in my town in a non-English speaking country. Shortly, it means that in a certain bar there are both the stage and musical instruments provided by us for anybody to use. It is in our interests to reach international guests to perform onstage, too, via Facebook invitations and status updates and such, in English, that is. I'm wondering what other words there'd be at my disposal in regard to referring to individuals and groups of people apt to perform on an open mic/stage night. So far I've been sticking to "performers". However, I feel that it's sort of too formal. Any suggestions? Should anybody have any experience in such events, I'd be grateful to receive propositions.
I think that performers is probably the best choice of word. Everything else I can think of would restrict the type of people you're looking for.
For example, you could say musicians, but then singers might feel excluded, and vice-versa.
You could say bands, but that might suggest you don't want solo performers.
Or you could say artists, but when used to describe musical acts, that tends to mean it's an established band or performer that people would know.
An entertainer (in British English at least) would normally be some sort of all-rounder: a single person who tells jokes, sings songs, dances, etc.
