10 Bands Who Were Justified In Changing Sounds

Another group with a staggeringly long history within the industry, Fleetwood Mac have amassed together over 120 million record sales and a place in the Rock N Roll Hall of Fame since their formation in London in 1967.

Having been assembled together from a group of artists heavily active in the genre beforehand, Fleetwood Mac's debut album, also named Fleetwood Mac, was actually a collection of original and covers of classic rhythm and blues-sounding songs.

Whilst the album helped launch the band's career with a no.4 place on the UK charts, it didn't contain any singles and barely scraped into the top 200 in the United States. The bluesy tunes would continue with the band's second album, Mr. Wonderful, in 1968, going a little bit further in fact with the addition of horns, keyboards and a live sound.

The unearthing of partners Lindsey Buckingham and Stevie Nicks in 1974 completely changed things for Fleetwood Mac however. The duo combined their immense songwriting abilities throughout their time in the band, but arguably brought the biggest shift in tone with Rumours in 1977. A far more soft-rock release featuring elements of pop, the album features some of the group's best ever songs, including Go Your Own Way, The Chain and Dreams and eventually went onto sell 40 million copies.
