Anfield have only got the permission for 5 years for concerts. Beyond that it'll be resident dependent if they apply again. Both can still hold concerts though if it comes down to it. You get summer gigs at both Manchester football stadiums.
I don't think stadium gigs are a game changer and certainly not the financial boom some may think. If we were realy serious about becoming a multi use venue we'd have had a USP like removeable pitch/roof as @Tom Hughes says. As it stands we'd be competing regionally with the Etihad and OT (cricket) as well as Anfield for big acts (forget about MUFC OT). We may have better facilities than Anfield, and you'd hope some design considerations have been made for such events, but Etihad will be on par and OT is very popular as it has a massive standing area.
Promoters do not allow most bands regardless of size to perform at both Liverpool and Manchester on the same tour (at least not on the same leg) so we'll have to work hard to entice acts to Liverpool from Manchester even when BMD is built.
