I've been listening to the Levellers for many years, since I saw them supporting New Model Army on tour back in 1990. I've seen them live numerous times, and they are always a storming live act. Unfortunately, their recent albums have been a bit of a disappointment. "Hello Pig" was the low point for me - barely a tune on it, and I struggled to listen all the way through once. "Green Blade Rising" was better, but "Truth And Lies" was another slip downhill - another one that I struggled to listen to more than once.
I bought "Letters..." yesterday, and was very pleasantly surprised. I'm not sure what's happened, but this is far closer to Levellers of old than the stuff they've been putting out since 2000. The tunes are actually catchy again, and there is a degree of energy and enthusiasm that has been sadly lacking in their recent work.
It doesn't quite reach the heights of classics like "Levelling The Land", but if (like me) you'd given up on Levellers over the last few years, this is well worth a listen.
