TTC customers are always pleasantly surprised when they hear the angelic sound of Chagall Sierra’s music flowing through a station. Chagall considers her voice to be her main instrument, often accompanied by a flute or singing bowl. Chagall's light soprano is romantic, ethereal, and spiritual with tones of folk and meditative sounds. Not only does Chagall love to perform, but she's also is passionate when composing music or writing lyrics. Chagall continues to work on several musical projects of her own, while being a TTC Subway Musician since October 2015.
