The Harvard University LowKeys visited Alexander Montessori School and entertained students, parents, and Faculty with an eclectic collection of music, ranging from classic rock to top 40, to rap, and everything in between.  The LowKeys, contemporary a cappella singers, were founded in 1999 by a group of ambitious students at Harvard University.  Alexander Montessori School received them with enthusiastic applause as they delighted and amazed us with their talent.
