I’m a nut for the “138” style of trance, and I’ve found some success with the “My Beatport” system where I follow artists and labels who CONSISTENTLY put out good tunes, rather than those who maybe put out 1-2 good tunes.
Live sets are a bigger one for me. Usually after Ultra and Luminosity, I’ll look for the live sets and tracklistings online, listening and shopping off them for the the tunes I liked. ReOrder, Darren Porter, John Askew, and Standerwick have been good sources for me lately.
I also think if you’re seeing a saturation of mediocre or cookie-cutter tunes on the web, then look into other sounds or genres. Try Psy-Trance, some harder hybrids of trance and techno, or whatever might float your boat.
