ime absolutely not. they magnify the banality of bad music.
that's what i've always found
nothing like as much of a psychonaut as luka, but i do remember one time on acid listening to Slowdive followed by Hendrix
now I like Slowdive... pleasant as far as it goes
but Slowdive was all shades of pale pastel colours - a palette of pinky-greys... their limitations, timbrally, were synaesthetically exposed
and then Hendrix (i can't remember which - probably 'Third Stone from the Sun' or '1983 A Merman) was the veritable explosion of colours - like Peter Cook as the Devil describing God in Bedazzled, "many-hued". his vast superiority (not a revelation or surprise, of course) was brutally underlined
another instance of the same gulf was the acid-enhanced contrast of Ozric Tentacles and Can's Soon Over Babaluma (Ozrics not my idea i hasten to add, my friend had that tape!)
drugs just expose the shortcomings of musical things ... you just are truly profoundly bored
