The last weekend of the 2014 summer season promises eats, beats and musical treats.

GET TRASHED

For the 2014 finale of Finale East Hampton, the nightclub will be bringing in Los Angeles DJ Tommy Trash to spin out its last summer Saturday. Large crowds are expected.

LAST GASP OF INDIE

FREE; 183 Edgemere St., Montauk, 631-483-5037, thesurflodge.com
