Well, it isn't Texas Music... but it is just as cool. Bartholomäus Traubeck made a series of seven recordings from different Austrian trees, including Oak, Maple, and this guy you are hearing, Ash:

"What you are hearing is an Ash tree’s year ring data. Every tree sounds vastly unique due to varying characteristics of the rings, such as strength, thickness and rate of growth."

The tree rings are relayed to a program that translates the rings into piano chords, which together form a beautiful arrangement. Cool, right? And slowly but surely this process is being translated into Texas Country. Maybe.
