This guy, Big Fin, is honestly one of the best musicians I've started listening to this year. He's currently Dry The River's guitar tech and supported them when I saw them at an intimate show in June, and his set was probably one of the best sets I've listened to. No gimmicks, just him and his guitar. The songs have a great sound both recorded and live - especially if you're into artists such as Dry The River - and the set was just so lovely because everybody was really quiet and respectful, no talking, which is quite rare at gigs, and especially during support slots.
Overall a really great set and I've since bought his Tether EP (which you can listen to/buy here) and absolutely love it. (Well, I can think of worse ways of spending £4 - absolute bargain!)
