I bought Random Access Memories, but after sampling some of their other albums, nothing caught my ear.
I can try again.

Ok, tried a little, same result.
Let's see if I can help steer you in the right direction:
Homework (1997) - Debut studio album - raw electronic/techno sound which reflected the French House genre. (
Around the World/Rollin' & Scratchin')
Discovery (2001)- Synth-pop disco inspired (Disco-Very) album. Some of the tracks use samples from classic disco tracks (
Crescendolls/Superheroes/Digital Love/Harder Better Faster Stronger).
Human After All (2005) - More repetitive and minimalistic than Discovery and robot-themed. (Technologic/Robot Rock).
Alive 2007 - This is a live recording of the Alive tour in Paris. They performed inside a massive pyramid lit with LEDs (see my profile pic), which changed colors and formed shapes in sync with the music. Their set is a mash-up of their previous albums.
Tron: Legacy Soundtrack (2010)- linked above
Random Access Memories (2013)- Won Album of the Year at the Grammy Awards.
