JÓHANN JÓHANNSSON.... I really really really like his works... Or at least what I know of his works, some soundtracks for movies like "Arrival" and "Sicaro". I have him in my favourite (todo) list at Spotify, but didn't really come around to explore his other works. Now listening to the one you shared, and LOVE IT! A strong push for me to start digging, for sure! :)

Regarding Photoshop. You know GIMP? Its open source and I use it from time to time when Powerpoint is not giving me the tools I need. Had a little trouble at first to get GIMP running on my Mac, but the recent version seems to work without me needing to tweak the OS under the hood.
