It's great to hear new material from Blur. Under The Westway is a lovely, cascading, gently epic ballad which could have been written/released during the Parklife/Great Escape-era. Damon's vocals are fragile, mournful and emotional. The Puritan, on the other hand, is a higher-tempo, electronic-laden, jaunty number which has more in common with 13-era Blur. Although it's good, Under The Westway is definitely the stronger of the two. On the CD single, there are instrumental versions of both songs, as well as a worthy acoustic version of Under The Westway.
For Blur completists, it's essential. Even if you're not a completist, it's a strong single and well worth owning if you're a fan. It would be nice if this studio work led to an album... but it doesn't look likely. In the meantime, I'll take what I can get and enjoy this single along with my new box set. There's something very special about the four of them together.
