On my second to last strong psilocybin experience I listened to
Sequentia's
Canticles of Ectasy, which is music by the medieval nun and composer
Saint Hildegard von Bingen . At the end of the trip, at 5 AM, I listened to
this [not this exact live recording, but this is the only one I could find online; apparently she's a homophobe now, but I still like her music, despite her deplorable views].
On my most recent strong psilocybin experience, which was around Christmas, I listened to a Bing Crosby Christmas album and had crazy green and red visions.
I often listen to Ayahuasca icaros from shamans I've worked with whilst I journey. It brings a certain ancient, slow, ayahuasca-y energy to the trip.
In the old days, when I was into Shaivism, I used to listen to
this a lot when smoking hash or tripping on mushrooms.
On a recent bad DPT trip,
this song by one of my favorite bands helped me keep it together
