Scottish band Mogwai got their start in 1995. They are not like many other bands, but were in a group of musicians from Glasgow during that period that were dominating the indie music scene for a while.
Most songs are long guitar-based, droning instrumentals. Mogwai loves to rock, both quietly and noisily. They often start out on one energy level, then the band all jump on their pedals and it becomes big musical noise.
This is a film made in late April of 2009. It’s called Burning, and has black and white footage of them playing at the Music Hall of Williamsburg, Brooklyn.
Cathartic in a modern, monolithic sense, it is best enjoyed loudly.
