If you get a chance to visit, you should, the city currently has about 50 murals by the likes of
Andrew Hem Angry Woe Bots Etam / Sainer Pixel Pancho Aryz Stormie Mills Roa Gaia Jaz
to name a few.
If you are coming from the SE, west coast or from across the pond I'd suggest flying into DC, seeing the amazing national galleries and then doing the 2 hour drive down to Richmond. Hotels are inexpensive, good food is everywhere and inexpensive and their own art museum and other history museums are worth the visit.
