First, you make '60s-ish lounge music. Then you remix it to high hell.

When playing a round of Runbow, the frantic nine-player Wii U eShop platformer due out on August 27, the bumping pace of the music is as much of a constant as the chaotic platforming and unique color mechanics. With influences ranging from swing to surf rock, Runbow's soundtrack features variety that fits perfectly with the Saul Bass-inspired visuals. It also includes a novel twist. When the levels are easy, each song plays normally, but when the difficulty ramps up, so does the music, as the zanier, off-kilter remixes take over.
Just go on over to developer 13AM Games' Bandcamp page (where you can buy the Runbow soundtrack RIGHT NOW) and check out "Tree's A Crowd," which is a fairly normal, peppy song. Then, go further down the soundtrack to "Leaf It on the Dance Floor," which takes the basic tune of "Tree's A Crowd" and transforms it into a jazzy modern remix. Several songs are paired in this fashion, making for a really dynamic soundtrack boasting lounge, blues, and everything in between and beyond.
"Sure, we could have licensed some ultra lounge tracks and remixed them, but we wanted to make it sound familiar but completely new and unique to the world of Runbow," said composer Dan Rodrigues about the reasons why he and 13AM Games' Dave Proctor made the original music.
In a few short days, Runbow will launch on the Wii U eShop in North America on August 27. While you wait, check out the soundtrack and get ready for our review on August 26.
