NYCGO created a great page highlighting venues throughout the 5 boroughs and major events.
Summer concerts will kick off for me on June 5th at Governor's island with Yeasayer. I fell in love with the band's vocals when I first saw them with Amanda last summer. This will be my first concert at The Beach @ Governor's Island. Their cite claims it to be the best place to see rock'n'roll outdoors and I hope they live up to their hype, outdoor venues can be hit or miss depending on the acoustics.
Have a great night!
