Planet Oz is the only solo studio album by German singer and songwriter Inga Humpe, released by East West in 1991.

Background
After the disbanding of Humpe & Humpe, a duo with her sister Annette Humpe, Inga Humpe embarked on a solo career and moved from Germany to London in 1989 to work with English musicians. Her debut single, a cover of "Something Stupid", was released in November 1989. In June 1990, "Riding into Blue (Cowboy Song)" was released as the lead single from her forthcoming album Planet Oz. The song was written and produced by Trevor Horn. It achieved radio play in the UK and peaked at number 93 in the UK Singles Chart.

Planet Oz was released in Europe on 21 September 1990, but its UK release was held back until February 1991. Speaking to The Independent in 1991, Humpe said of the album, "I had 20 songs ready and a clear idea of how I wanted them to sound. [They sound] artificial somehow... you could say the music is a house or a landscape for my voice. I think with the next album I could go much further rhythmically." The second single, "Do I Have To", was released in January 1991 but failed to chart. A cover of a Pet Shop Boys B-side from 1987, Humpe came to record the song after a chance meeting with the duo. Humpe revealed to The Independent in 1991, "I think they're the best pop songwriters. They were working in the studio next door and we met by chance. They suggested another song for me, but I liked 'Do I Have To'. It's the story of a love affair with three people."

Critical reception
Upon its release in Europe, Music & Media described Planet Oz as "fairy-tale synthesizer pop" which "specialises in ambient ballads and sophisticated dance songs". They noted Humpe's vocals as "sweet, with a naive, childlike quality" and added that the album sounds like "a cross between Kate Bush and Grace Jones, without the mystique or flamboyance but still possessing a dream presence". In a review of the "Riding into Blue (Cowboy Song)" single, John Morgan of the Derby Evening Telegraph noted, "The song opens with a nifty, swinging rhythm and Inga's sweet vocal harmony parts adding an air of intrigue to what sounds at first to be a countryish number. But the piece offers much more than that, and develops an almost surreal aura." Craig Gavin of the East Kilbride World reviewed "Do I Have To" in 1991 and commented that it was a "surprise", having not been familiar with Humpe and so was not "expect[ing] too much". He did not think Humpe had a "great voice" but added "it's certainly unusual" and felt the song suited it. He stated, "I look forward to hearing more from Inga – and I hope that all her future numbers are so well chosen."
