Agreed. As a guitarist it means a lot and is a great learning tool to be able to know exactly what someone's playing. I wish more guitarists in the scene would talk about playing more. I've never listened to this band but it's cool that they did this.
I agree that it is a good learning tool. While learning by ear will require you to be familiar with the sounds of scales, tabs for a band like this that are not usually found online, coming from a direct source, will really give an excellent starting point for styles and scales.
Imagine Algernon and Snowing tabbed by them.
