Funk Turkey used lyrics.rip to scrape the Genius database of Nirvana lyrics and then set a Markov chain bot to work generating lyrics to a new "Nirvana" song. Funk Turkey made the music and sang the bot's poetry. Listen to "Smother" and spot the actual Cobain phrases! From the YouTube description:
All music/vocals performed, mixed, and mastered by me, in my kitchen, on a sparkly red cheap Stratocaster, a crappy mic, and an old copy of ProTools. All lyrics provided by Hal 9000 (AKA lyrics.rip). Guitars are the aforementioned Stratocaster bounced hard left and right. Flanged Stratocaster through a Fender twin is dead center in the mix. Bass is a no-name bass run through amp emulation. Percussion is Superior Drummer 2. I know Dave Grohl hates computer drums but it's the best thing I got, soooo…. Sorry Dave. I still love you.
Vocals are doubled, slightly compressed, and run though an emulated reel-to-reel and tube saturation for a bit of extra warmth and grit. Also the first use of my new pop filter that my wife bought me for early father's day. She's the best.
