I love the Canadian group Walk off the Earth. They started as a cover band, but they are an exceptionally talented group and their videos are very entertaining. Here is what
Wikipedia says about them:
Walk off the Earth is a Canadian rock band that was formed in 2006 in Burlington, Ontario, and has gained success around the world by making low-budget music videos of covers and originals. The band built its fan base independently with no help from record labels, booking agents, or management. In February 2012, the music industry publication Crazed Hits reported that the band had signed a recording contract with Columbia Records.[1] The band is best known for its covers of popular music on YouTube, making use of uncommon instruments such as the ukulele and the theremin, as well as looping samples. The band's recorded music and videos are produced by member and multi-instrumentalist, Gianni Luminati Nicassio.
And here are a few of their most recent videos. I swear these guys just keep getting better!
