I had my younger sister listen to psytrance with me since she was 10-11 years old.
I mostly listened to Astrix, Silence Hill, Dali and other full on shits, but eventually moved to Goa Trance.
She's 19 now, and even though I dont live with her, sometimes I sent her some tracks from Youtube for her to listen, to see if she remember them. She told me she liked some tracks I've sent her like : Yahel - Waves Of Sound, Infected Mushroom - Becoming Insane, The Muses Rapt - Spiritual Healing, Shpongle - Doors of Perception, some darkpsy like Fragretrollet - The Forest Spirit, Nechropsycho - Macabra Queen and even some freaky Psycore like CinderVomit - Is This A Dream?...
