If you like chill music with some cool acoustic guitars, then check this band out:

Six organs of admittance

Here are some of their best songs:

Procession of the cherry blossom
Lisboa
Saint Cloud
Words for two
Close to the sky
Hazy sf
You can always see the sun

So the next time you're about to smoke some ganja, do it and then listen to these songs. I doubt you'll be displeased.
