In his early 60s, Rob Kaufman suffered a medical emergency that caused him to faint and hit his head on a wood floor, resulting in a traumatic brain injury.

He was put in a medically induced coma, his wife Ellen recounted to Agence France-Presse (AFP), and was in intensive care for about a month. Nine weeks of extensive rehabilitation including speech therapy followed and today he experiences significant short-term memory loss.

Music therapy proved invaluable in the rehab of the onetime studio musician who said he has played for the likes of Jimi Hendrix.

And today, the Kaufmans are regulars at a Manhattan concert program designed for individuals experiencing dementia symptoms.

The couple recently attended a 10th anniversary performance of the program that featured the Calidore String Quartet.
