Are you a soloist with backup Musicians? Are you a member of an ensemble, aka: Band? Sometimes when one member of a group, aka: Band, is considered by all to be the business manager, that member accepts remuneration as an extra percentage. For example, if there were four members of the ensemble, then the profits on the CD might be split 5 ways with the business manager accepting 1/5 as a performer and 1/5 as the business manager.
   Each member of the ensemble should have an equal voice in how all business matters are handled. If they do not, perhaps the Musicians other than yourself should be under contract else they might sue you for future profits on CD sales, even when they are no longer performing with you. If you think of yourself too highly to be equal to the other members of the ensemble, perhaps you need to rethink the ensemble.
