Re: Can i charge?
If I was warned about this ahead of time, I might build an extra charge into my cost. If they sprung it on me after negotiating a fee, I think I'd be "busy" already at that time. This sounds like a request from an inexperienced artist. I don't fall into that category (at least in all the common genres of music), so I think I'd try and avoid attending rehearsals if I could.
If the show was something complicated (a musical, for instance) that required tech rehearsals, that's a different case, but I would expect to be compensated for those rehearsals.
It sort of reminds me a of a local drummer who was hired to play for a week or two of club dates with an out of town artist. The artist booked rehearsals with the local band, but the drummer had some other gigs that conflicted, so he sent a sub. Artist was not impressed. :twisted: The drummer pulled off the gigs, and was hired the next time Artist came to town, but was told "no subs" for the rehearsal the second time.
