We loved Janelle Monáe’s The ArchAndroid. Quentin Huff said, “Welcome to Metropolis, folks. The year is 2719, even though the music is being released in 2010. It’s funky and fantastic, futuristic but retro. It’s in a category of its own.” Here’s a new mix of “Tightrope” with B.o.B and Lupe Fiasco, the earlier version featuring OutKast’s Big Boi.
