Yes, it is, and he clearly understands chord structure too! I know Mark has written a share of the guitar parts, but now it's looking like all three of them are sharing in every aspect of the song writing. This is really exciting!
Travis wrote some guitars on the S/T album as well
I didn't quite feel a boxcar vibe on anything like I was hoping but first listen, not bad. Production quality sounds way better than Neighborhoods so I'm happy.
This just gets me that much more excited for this. I'm feeling vibes from about every aspect of their careers on this. I enjoyed Neighborhoods for what it was, but this sounds amazing so far!
