What’s the difference between music of the 1770s and music of the 1970s? According to The Piano Guys, just enough to create a really fantastic mash-up. And so they did.

The group’s latest music video, released on YouTube Tuesday, is the most psychedelic throwback yet to grace the interweb.

Titled “What if the 1770s collided with the 1970s? – ‘I Want You Bach,’” the four-minute video features the alter-egos of musicians Jon Schmidt (“Duke Johann van Keymeister” and “Phil”) and Steven Sharp Nelson (“Sir Reginald von Sharp” and “Scooby”) in a Bach and Jackson 5 mash-up that will make you wonder why the two centuries never met before.

Here’s what The Piano Guys had to say about their inspiration:

“What if the harpsichord from the 1770s hit headlong into the talk box from 1970s? What if J.S. Bach and Jackson 5 met up and just jammed? Would they jive? Can you dig it? These are the kind of far out questions we asked ourselves as we laid down these licks and cut this film. We decided to put together a gig with two wigs in dandy attire and two hep-cats in some funkadelic threads to see if it would fly. … Presenting … ‘I Want You Bach’ – Jackson 5’s funky ‘I Want You Back’ mashed-up with 5 illustrious themes written by J.S. Bach.”
