Their albums are disappointing but do a best off and it's great stuff. Lot of bands like that nowadays.
I love the theory behind the use of the capo on seventh fret, as it can make a song more interesting, especially if you don't have good vocal chords to accompany your playing. I tend find it makes it what I call more harmonic... A particular song this is useful for is Creep, where you really do need to be able to accompany it with singing. For me the way round it is to place the capo on seventh, and then use chords C, Cadd9, E, (E7?), F but not as a barr (Melanie Martinez style), the FM as a barr. As the guy demonstrates as one of the methods in this video... But if you can sing, scrap all that, and run with this guy, the best version by far...
