A hard-luck blues band of the '60s, Canned Heat was founded by blues historians and record collectors Alan Wilson and Bob Hite. They seemed to be on the right track and played all the right festivals (including Monterey and Woodstock, making it very prominently into the documentaries about both) but somehow never found a lasting audience.
Inspired by folk, rock, country, and bluegrass, the London-based, platinum-selling Mumford & Sons feature singer/guitarist/drummer Marcus Mumford, vocalist and banjo/Dobro player Winston Marshall, vocalist/keyboardist Ben Lovett, and vocalist/bassist Ted Dwane. The foursome started playing together in 2007; though they were playing with other bands at the time, they bonded over their shared love of rootsy music.
IQ are a British neo-progressive rock band founded by Mike Holmes and Martin Orford in 1981 following the dissolution of their original band The Lens. Although the band have never enjoyed major commercial success and had several line up changes, IQ have built up a loyal following over the years and are still active as of 2016. In 2011, IQ performed a series of concerts in the UK and Europe celebrating their 30th anniversary.
