The Boston Jewish Music Festival holds concerts, lectures, and other educational events to promote Jewish culture.
On March 12, 2011, the Boston Jewish Music Festival featured a concert, "Divine Sparks – Music to Ignite Your Soul: A Concert of Kavanah," in which Lemmer performed.
 Bill Marx, editor of The Arts Fuse, a Boston-based online art magazine, wrote:
"All of the judges found the concert ambitious and fascinating, a valuable step in expanding the creative and cultural boundaries of "Jewish music."
The cantors were generally admired, with the recognition that they sang with great devotion, spiritual power, and a proud exuberance."
