It'd be nice if the ERD indicated PKs for each table.  It'd also be good 
to explain the relationship between artist, person, & band, since it's not 
obvious.  There is an implied constraint that a given artistid must appear 
in either the band or person table, but not both, I think.  That's pretty 
crucial to making this particular schema make sense.
