Lately I have been trying to listen to a lot of bands, basically being open to a lot of ideas hoping to form new and better ideas myself.
Some of the bands that have really appealed to me are mainly aren't very heavy but are definitely beautiful to listen to.
Porcupine tree is one such band which can be categorized as psychadelic rock.
I got addicted to the band when i heard songs like lazarus, lightbulb sun. They are able to form a very good concoction of acoustic and distorted sounds. The album "the lightbulb sun" is mainly acoustic and is one that appealed to me a lot.
The newer releases by them are slightly more on the heavier side none the less they have not lost their charm.
