from which aspect did he judge?
if he didn't make it clear he was just talking bullshit.
well from the projects that you mention astral,mfg,im one guess is that if you are a couch potato then you will definitely like hallucinogen more at once cause the energy in his compositions is not that obvious.(in terms of serotonine stimulation)
astral,mfg,im ,you know,they have that super strong kick,the driving insane basslines,they have the tracks that make you say at once : THIS IS POWER! LET'S DANCE!
of course they are psychedelic too.
the point is to explore the magic that every artist is hiding in his compositions.
there is also taste ...
