The "old gods" had lots of talent. Back then music was made with hardware, which was expensive. So to actually make a basic track you would need to buy hardware for several thousand euros. If you were prepaired to make that investment you probably already had some talent. Today, the cost of making a track is the cost of a computer. The results, anyone can make music, and that doesn't lead to quality, it's leads to quantity.
I realise now, that the cost of equipment probably hade another consequence: many acts were two or more members. Pleiadians/Etnica, X-dream, Total Eclipse, Slinky Wizard, Juno Reactor, Koxbox, Quirk, Technossomy, UX. Why could this be relevant? Because more members lead to more influences and more ideas. I can think of a handful of neo goa acts that consist of two or more members,
There were a lot of creativity and as psytrance spread over the world, people added their ideas to the music, and the music kept evolving. Suntrip has been releasing neo goa for 13 years now, and in my opinion, the sound hasn't changed that much during that period. I'm sure others will disagree. The production quality has however increased, but that sound is more or less the same. In short, the "old gods" get worshipped because neo goa is a modern take on that old sound.
I have a public Spotify playlist with what I consider to be the best melodic sunshine neo goa tracks, and even though I've scanned 13 years of neo goa tracks I haven't found more than 20 great tracks. I do realise that some great tracks are missing on Spotify. Feel free to follow that playlist if you want to know what tracks an old timer enjoys. I often listen to that playlist when I'm running.
