I discovered Goa Trance in 1996 with the first Pulse compilation and was immediately hooked to this music. I started to buy all the cds i could get at this time (and it wasn't that much my record store had to offer at this time).
One of the albums i bought in the beginning was "Global Psychedelic Trance Vol. 2" by Spirit Zone, the second cd containing chill tracks by Pleiadians, X-Dreams, The Infinity Project and Patchwork. So i think this was my introduction to psychill. At this time you didn't find too many chill albums, but often the closing track of an Goa album was chill.
I always loved the Trance music as well as psychill, but with the years my focus is more and more on the chill side, enjoying dance music mainly at festivals today (and also there i spent more time at the chill area). There is just more musical variety and emotion in the chill music compared to the four to the floor formula.
