Some of the best instrumental post-rock comes from Chicago. I’ve delved into this genre enough to start recognizing patterns and Chicago is where it’s at for this stuff. The Flashbulb is a band of master tone crafters. They have plenty of albums well worth checking out, “Opus At The End Of Everything” being the most recent, but I will focus this review on their 2010 effort, “Arboreal.” I believe it’s a great first exposure to this band if you haven’t already heard of them. If you have, make sure you haven’t forgotten about this beautiful album.
