The Lowell Summer Music Series is a not-for-profit program that offers concerts on Friday and Saturday evenings under the stars in a beautiful outdoor amphitheater. The lineup so far for the 2013 season is a perfect display of the diversity and quality of the concerts, including Michael McDonald on July 13 and Kenny Wayne Shepherd on July 19. Additional shows are already on sale. For more information, visit www.lowellsummermusic.org.
