Wow, lots of electro love on this site. Not quite my thing, but I can dig it.
I won't make an official because I am still a novice vaporist and, after all, the topic demands cool music to vape to; I've only listened to a limited amount of music under the influence of MJ vapor.
HOWEVER. I have lounged to some Chico Hamilton Quintet, John Frusciante (listened to an Omar Rodriguez-Lopez Quartet with JF album on vinyl last time I vaped), Medeski, Martin, and Wood (awesome acid-jazz-funk trio), and Brian Eno lately. Brian Eno's Ambient 1: Music for Airports is sooo spacey. I haven't yet made it through both sides of that record without falling into such a relaxed state as to succumb to sleep.
Will get back to y'all when I've listened to more music after vaping. ;D
