So, I am in a new band, it is still being built, as we need drummer/singer. But, my question is this: One of the guitarists is my little brother, soon to be aged 16. Will this become a problem when/if we start playing gigs? I assume that he could still play any bars or 21+ stuff, since he is part of the band, but does anyone have experience with this sort of thing? I really want this to work, we are all so far serious musicians, and share the ultimate goal of "getting big" so to speak.
