Anyway, here's the track (Timmy Trumpet - Oracle)
ETA here's a current working URL: https://www.youtube.com/watch?v=__TvPr_Wtvc
I got it out of another of the Ummet Ozcan Innerstate mixes (https://soundcloud.com/innerstateradio/ummet-ozcan-presents-innerstate-ep-113) which is OK overall but this track is so different it grabbed my attention.
I have lots more music to post but this mystery has been bugging me enough that I wanted to pull it out.
ETA: Solved! sovay identifies and links - see comments.
ETA2: Another (anonymous) commenter points to a different track. See also below.
