Hello mate,
Chris from the band here.
1)You can cover "Red Shift" no problem. If you release any of our tracks commercially in a release or play any song live, it's the author's society that'd keep a small proportion of your "mechanical rights" for whoever created the song (ahem, me).So no problem
2) We're not into making tablatures, but for the key section I guess you can find some info around one of those weirdos' tablature sites.For "Red shift" we were tuned to D, so I'm sure you can follow the guitar tracks easily.
Thanks a lot!!! It's great to know someone's interested in doing a cover!!!
