At the end of 2015, we lost Lemmy, the charismatic frontman of Motörhead. A few days later, David Bowie released his fantastic album, Blackstar, only to die two days later of an 18-month battle with cancer.

It was (and is) hard to deal with the passing of two of music's greats, but folks are finding a way to pay tribute to both. The latest is an incredible mash-up called "Ace of Space." Listen to it above.

YouTube user Andy Rehfeldt managed to combine two of each artist's biggest hits, Bowie's "Space Oddity" and Motörhead's "Ace of Spades," for a moving work of art.

After you press "repeat" a couple times, we recommend peeping this Lemmy gallery, and listen to our list of 29 essential Bowie originals.
