The second annual May Day “Mayday” Festival goes down in Long Island's Southaven County Park on May 9 with Deer Tick, Dave Hause and the Mermaid, Justin Townes Earle, Spin Doctors, Sahara Moon on the bill, with more acts still to be announced.

The festival is put on by labor organization The Suffolk County Association of Municipal Employees and here's a little more about the festival:

As New York State’s largest independent labor union, the Suffolk Association of Municipal Employees is organizing the May Day “Mayday” Festival in the spirit of singer activists like Woody Guthrie and Pete Seeger and modern rock artists who have carried on their tradition, successfully capturing the voice of the working class hero.

The May Day “Mayday” Festival is being organized to raise awareness of the issues facing working people today and to promote solidarity not only across labor unions but between all people who work to provide for their families. Considering this purpose, we are proud to have the support and partnership of our brothers and sisters from the Long Island Federation of Labor, AFL-CIO.

Tickets are on sale and all net proceeds going "to fund charitable causes—from scholarships for union members and their families, to promoting union organizing and activism, to putting food on our neighbors’ tables by supporting Long Island Cares: The Harry Chapin Food Bank.

Justin Townes Earle will be out on tour with Brian Fallon and Worriers this spring; Dave Hause is on tour as well. Deer Tick’s John McCauley appears on the upcoming Local H album and plays a one-off in Nashville this month.
