Some variations on performers and audiences
Though it has been around from at least the 13th century, the concept of the one-man band is still something of a novelty, especially when performed as well as this:
One person playing four or five instruments isn't completely unfamiliar, but I'm not sure the reverse is true. Canadian band Walk off the Earth, with Creepshow's Sarah Blackwood, experimented by trying five people on one instrument. Covering Gotye and Kimbra's 'Somebody that I Used to Know,' the quintet gives an incredible performance where both the song and video are as intriguing as the original.
Another cover, this time performed by last century computers. Featuring oscilloscopes and an old HP scanner, YouTube user bd594 creates a disturbingly perfect rendition of the Animals' 'House of the Rising Sun.'
As any musician with a pet will agree, finding an animal audience can be difficult. The sounds and patterns that we prefer are not shared with too many other animals. The beluga whale may indeed be one of the few.
An Earth-space duet? It's amazing how International Space Station astronaut Cady Coleman and Jethro Tull's Ian Anderson make such a remarkable event look like it's something they do all the time.
As a music store employee, one is audience to countless performances from a wide array of musicians, tuneful and otherwise.
