First let me start off by mentioning a really great guitar duo that plays all around the area in various restaurant locations.
They are Two For The Road.

Check out their website, and you will find their playing dates and even some samples of their original songs, as well as videos of cover songs. During the summer they play right on the boardwalk down in the very northernmost end of Seaside Heights, and it is so nice to go hear them there. It's great to sit on the beach, dig your feet into the sand, and listen to some great music. Of course stopping at Wawa first and getting yourself a big huge coffee doesn't hurt!
So once I get all my summer activities organized, I'll podcast about each of them. We do SO much this summer, so hopefully it'll help you out as to what you're looking for down the shore so you can make the best of it!
Until then.....
