Between June 27th and July 12th, Rotterdam will be all about jazz. During the 4th edition of the jazz festival North Sea Round Town, visitors can attend over 150 concerts, exhibitions, jam sessions, masterclasses, lectures, in-house concerts, jazz boat tours and after-parties. Check out The Jazzinvaders July 3rd at De Unie but there’s a lot more worth checking out. What about Hot Brass 8 Band, Jose James, Ben Westbeech, Kim & Erwin Hoorweg?
