Search your favourite artists. Wiki them etc. and learn about them whilst simultaneously finding where they’re members play in other bands or have other projects. Also, it can illuminate what they’re influences were/are and you can listen to that too. I find a shit-tone of new music this way.

Radio Paradiso. Berlin based radio. Weird and wonderful.
