There are many places in New York to see a concert. 

The most famous place is The Madison Square Garden but there are Time Square, The Radio City Music Hall and the Webster Hall.

In New York it exist live entertainement bar. This is very cool to see a jazz concert and drink with friends.

I have been in an Iron Maiden's concert with my best friend because we love their music and it's pretty cool to come in a concert with his or her best friend to enjoy.
