The Grand Illusion presents a screening of the new documentary about post-rock pioneers, Mogwai.   Over 25 years and 10 studio albums—using powerful sonic force mixed with subtlety and grace—Mogwai have defined their own musical genre and built a cult following. IF THE STARS HAD A SOUND takes us on a journey from their very beginnings, in the mid 1990s, to creating their tenth studio album in their hometown of Glasgow in 2020. While at first seemingly impossible to make, they ultimately made history with it.
