Grails
I have to admit to have been swept up in the whole Post Rock sound a few years back but as time has gone on I have found 75% of the bands far too bland and formulaic to continue listening but every once in a while a band pops up that dares to sound that little bit different and take their influences from other areas of music other than the classic Post Rock sound of crescendos and ambient breakdowns.
Grails are such a band. Taking their influences from Psychedelia, Folk and Jazz they at least have a modicum of identity and appeal to many moods.
If you are looking for something a little different from instrumental bands then give this album a listen.
