Carlos Santana collapsed on stage during a performance at Pine Knob Music Theatre in Independence Township, Michigan on Tuesday night.
A concertgoer shared a video that shows a medical team being brought up to help the 74-year-old guitarist off stage. The rest of the show had to be canceled.
Santana's manager Michael Vrionis said he had heat exhaustion and dehydration. He was taken to a hospital for observation and was "doing well" as of Wednesday morning.
His show scheduled for Wednesday in Burgettstown, Pa. was postponed.
