Post rock and prog rock are very different, however they both share an experimental nature. Having gotten used to irregular time signatures through prog rock, I was disappointed to find that the majority of post rock artists tend towards conventional time signatures.
I'm sure it can be argued that this fits into the style and motives of post rock artists, however I was wondering if any post rockers have been known to use irregular time signatures in their work. I'm particularly interested because signatures such as 5 or 7 are often associated with being quirky, technical, or energetic and I've never heard them being used in a more laid back or shoegaze style such as that of post rock.
Are there any examples of post rock songs written in irregular time? I'd be interested in giving them a listen.
