David Bowie performed at the Boston Garden in Boston, MA, on 17 March 1976, as part of the Isolar Tour.
It was the 34th date of the tour, which began on 2 February in Vancouver. It was also the first of two consecutive nights at the venue.
His guitarists were Carlos Alomar and Stacy Heydon. Tony Kaye was on keyboards, George Murray was on bass guitar, and Dennis Davis was on drums.
Bowie returned to the Boston Garden on 6 May 1978 during the Isolar II Tour.
I distinctly remember hearing Bowie play “Sister Midnight” that night.
