When Galilea is casting for roles, auditions are open to everyone who is interested, and auditions for one role does not prevent auditioning for another.
In short, feel free to audition for as many roles as you wish.
All audition files should be recorded in MP3, baseline quality at 44,100hz, 128kbps (These are the default settings in most recording programs such as Audacity). Include as many takes as you desire, with different variations on emphasis, accent, and emotion.
Lines should be e-mailed to firstname.lastname@example.org with the subject line [Galilea Casting], followed by your name and the role you are auditioning for. This will prevent confusion and also prevent the e-mail from accidentally being eaten by junk filters.
