Sorry but this is a really confusing review.
On one hand you praise this record musically but on the other seem to be unable to decipher the difference between an EP and an LP and therefore somehow feel let down by it's 'brevity'.
Now In what I can remember of my time listening to music. An EP generally consists of 4-6 tracks and weigh's in around 20 mins or so, no? So how can you feel this one 'falls short' because of the very reason which makes it an EP release and not an LP? Unless it was somehow advertised as an album? Which it clearly wasn't.
Considering you seem to speak quite highly of the actual quality itself, the hang up about the shortness ( of a twenty minutes plus EP which includes a DVD )is Really strange. How long do you expect your EP's to be exactly? Just my opinion of course.
