Subbed for a big band well above my current level. I was intimidated but determined not to chicken out, whatever the results. I did my homework and actually pulled it off. Made new contacts, got some flattering comments. For many of you, this will seem kinda lame, getting all excited when it's not even an audition. But for me, it was a TRIUMPH! PS: They are still above my level really, but I learned the arrangements and read like a mad thing, which proved more valuable to them than skill alone.
