I like ambient music without vocals for when I'm working, since I find hearing words distracting. You might like these if you like Tycho.

• 2 Mello has a range of albums that are chill hip-hop, like Sunsound Collisions and midnight broadcasts vol. 1
• QUADRATA by Oyster is Boards of Canada-inspired downtempo
• Interstitial Geometry by Insectoid Intelligence is some ambient electronic roughly in the dark and drone corners of the genre
• Kitten Burst by Jam2go is the soundtrack for the game Kitten Burst, also by Jam2go. It's split into five albums. The set as a whole is a wide-ranging tour of Y2K-era electronic music, from liquid drum & bass to eurodance to house.
• From nobonoko, there's Music For Animal Cafés, which has a warm and cheery sound to match its name, and Television, which is more minimal electronic
• Floating Points makes chill house music that's kind of hypnotic, like Someone Close and Nuits Sonores

If you like Old Giant, check out MASTER BOOT RECORD's albums, like INTERRUPT REQUEST. It's prog metal that incorporates old PC sound chips.

And for some totally weird stuff:

• Oscilloscope Music by Jerobeam Fenderson is music designed to produce animations when shown on an oscilloscope. Here's a video of one of the tracks! The album feels like it's poking your brain when you listen with headphones.
• van by clown core is… something. Grindcore with sudden switches to jazz and screaming.
