Funny one this as it is something I should really like but can't get into for some reason as yet. The music is clearly beautifully crafted, cleverly written and excellently recorded. There are sufficient obvious overlaps with bands I really like (Talk Talk, Low, Bon Iver, Shelleyan Orphan and even aspects of Sigur Ros) but there is something missing at present for me.
I've seen this described as part of the Baroque Indie scene (particularly with the Bon Iver thing but there are reminders of Soulsavers in the music too) but it really appears to be more a folk/prog thing with a healthy dose of ornithology thrown into the mix. It is very interesting so I am going to listen to the rest of their back catalogue. More intriguing is the fact that Shearwater appears to be a side project for another outfit I know nothing about called Okkervil River who I also intend to listen to.
So, currently a 3/5 for the LP itself which I think is OK, but a bonus point for putting me on to not one, but two potentially interesting bands. Usually a 4/5 reflects the fact I buy the LP which I haven't done yet, but this may well end up being expensive as both Shearwater and Okkervil River appear to have extensive back catalogues.
(EDITED to add a Fuck You! to @browellm as the Okkervil River stuff appears to be magnificent and will need purchasing . There is loads of it too, obviously )
