Re: Strange little professional problem
That's like Sting asking Vinny to chip in for studio time on his next album.
I would hope,you have a contract,which stipulates your duties and salary with the band as a non member.Time is money and if anything,you should be getting paid to rehearse,and certainly not paying to do so.
It should also spell out that you are NOT paying to play,but are in fact,playing to get paid,and for a certain amount in compensation.on such and such a date and time.
This band "leader" seems to have his wires crossed.
