Mate, not gonna lie, I'm absolutely lovin' this. I'm fairly new to synthwave itself - in fact, it was Klayton's name attached to Scandroid & that Groupees bundle that got me hooked only a few months back. I've always had a thing for the electronica & industrial game OSTs (A.R.E.S., Explodemon, the Fahrenheit Project, Frank Klepacki's Command & Conquer, Jonathan Greer's Neon Chrome (which is proper synthwave), and Mick Gordon's Doom 2016 are all on my current playlist). Machinae Supremacy's Commodore SID-inspired blend of metal and retro game music is an old favourite (they actually did the OST for Jets 'n' Guns) and, although seriously industrial rather than electronica, it was Quake 2's soundtrack by Sonic Mayhem that got me to pick up a bass guitar 20 years ago (fuck me, that was 20 years ago?)!
Regardless, that's all history (though, along with Celldweller, I guess it made synthwave an easy step for me); I'm really enjoying getting into the darker synthwave stuff now too. It's fucking awesome finding new names to check out; further down the rabbit-hole ahoy!

In a completely different tack, runner-up for Band of the Week™ is Animals as Leaders (and I guess, by extension, Sarah Longfield too). I mean, it's all fucking prog-djent guitar wankery, but it's guitar wankery at its best.
