A promo video for Chicago Music Exchange fires, in one seamless take, through 100 guitar riffs from the past 60 years in chronological order, from old standards by Johnny Cash and Buddy Holly to today's standbys by Mastodon and St. Vincent.
The group Walk Off the Earth performs the song "Somebody That I Used to Know," originally by the Australian singer-songwriter Gotye. The catch? They all play on different parts of the same guitar.
It'd be easy to dismiss the five-musicians-one-guitar schtick as a gimmick, but the group actually creates a beautifully-executed rendition of the song in its own right, perfect for listening if you're celebrating Single's Awareness Day today.
