Solarstone has made a name for himself in the trance scene for his commitment to Pure Trance via his record label of the same name. It only made sense for him to launch a radio show/podcast of the same name as well.
If you haven't figured it out already, when you create a trance label, the trend is to create a radio show/podcast to showcase the music. Thus, Giuseppe Ottaviani has created Go On Air radio to match the label of the same name.
The Future Sound of Egypt label has been prolific in bringing trance of the uplifting kind as well as trance from around the world with direction from Aly & Fila. It only makes sense to share these vibes through the radio show/podcast of the same name.
It should go without saying, but this blog would be remiss if A State of Trance (ASOT) by Armin Van Buuren was not listed. This very popular radio show/podcast has done a lot for the trance scene as a whole, and it is all thanks to Mr. Van Burren.
