I admire musicians who simply can do more than singing but also play their own musical instrument. Some even use extra tools to make everything sounds even better. Just like the mod-kits-diy effects at musicians friend .
Here in Ireland, plenty of pubs, bars and restaurants offer this kind of entertainment. I'm very much sure that you won't be disappointed hanging in one of the famous spots here. Irish music is very rich and will surely makes you feel good.
So when your in town, remind yourself to visit places like Temple Bar to experience great time in Ireland.
