Little Shop of Horrors is a rock musical by composer Alan Menken and writer Howard Ashman, about a nerdy florist shop worker who raises a plant that feeds on human blood. The musical was based on the low-budget 1960 black comedy The Little Shop of Horrors, directed by Roger Corman. The music, composed by Menken in the style of 1960s rock and roll, doo-wop and early Motown, included several show-stoppers including "Skid Row (Downtown)", "Somewhere That's Green", and "Suddenly, Seymour", as well as the title song.

In addition to the original long-running 1982 off-Broadway production and subsequent Broadway production, the musical has been performed all over the world, including in Buenos Aires, Sydney, Vienna, São Paulo, Toronto, Copenhagen, Helsinki, Paris, Berlin, Athens, Budapest, Reykjavík, Jerusalem, Rome, Tokyo, Zurich, Athens, Barcelona, Cologne, Mexico City, Auckland, Oslo, Singapore City, Johannesburg, Madrid, Stockholm, Seinajoki, Akureyri, Vaasa, and London. The musical was also performed in Bogota, Colombia in July 2008. Because of its small cast and relatively simple orchestrations, it has become popular with community theatre and high school groups.TIME magazine reported in its May 26, 2008 issue, p. 51, that this musical ranked as the most frequently produced musical by U.S. high schools in 2007. The musical was also made into a 1986 film of the same name, directed by Frank Oz.
