full_context: Document 1: Uriah Heep discography: Over the years, the British hard rock band Uriah Heep has released 24 studio albums, 13 live albums, 16 compilation albums, 27 UK singles (33 worldwide) and 17 videos. The band's best selling album is "Sweet Freedom" which was released in 1972 and its worldwide sales are more than 4 million copies. Uriah Heep's progressive/art rock/heavy metal fusion's distinctive features have always featured massive keyboards sound, strong vocal harmonies and (in the early years) David Byron's operatic vocals. Twelve of the band's albums have made it to the UK Albums Chart ("Return to Fantasy" reached No. 7 in 1975) while of the fifteen "Billboard" 200 Uriah Heep albums "Demons and Wizards" was the most successful (#23, 1972). In the late 1970s the band had massive success in Germany, where the "Lady in Black" single was a big hit. With Black Sabbath, Deep Purple and Led Zeppelin, Uriah Heep became one of the top heavy metal and hard rock bands of the 1970s. It was there that the solid, but rather mainstream-sounding "Sweet Freedom" (No. 18 UK, No. 33 USA) was created with "Stealin'" released as a single. Having gained worldwide recognition, the band quit using fantasy lyrics and made an obvious stab at versatility by adding funk ("Dreamer") and acoustic folk ("Circus") elements to the palette.
