Wrexham is actually really good and there are lots of people trying something different.
A really active and popular 'originals scene with interesting bands, plus a great blues thing going on.
There's also the Focus Wales' festival in Wrexham every April - check it out...........
There are also lots of pub covers bands and jam nights.
Additionally, there's Chester 20 mins away with some decent venues, plus Liverpool and Manchester are within an hour's commute.
