Nightingale
Albeit I am more familiar with Stein through his pony pseudonym, I find his non-pony musings to be some of his best works (probably due to my preference of pony music that doesn't hold too much pony allusions so it is harder to listen outside the specified context.) Away in the Sky is particularly the best I've heard from this artist as it has the richest and widest atmospheric and contextual interpretation so far. To prove my point, try listening to this track during sunset flights.
