(CBS) Fans of underground music were dealt a double blow today as news came out that both Phoebe Snow and Poly Styrene died today. Many expressed their emotions online through tweets and Facebook posts, remembering the icons for their contributions to the music world. Snow was a American singer, songwriter and guitarist. Her biggest hit, 1975's "Poetry Man," showcased her contralto, four octave blues-tinged vocal talent. She died from complications from a January 2010 brain hemorrhage on Tuesday. "The loss of this unique and untouchable voice is incalculable," her manager said to Extra. "Phoebe was one of the brightest, funniest and most talented singer-songwriters of all time and, more importantly, a magnificent mother to her late brain-damaged daughter, Valerie, for 31 years. Phoebe felt that was her greatest accomplishment." Phoebe Snow, "Poetry Man" singer, dies at 60 Many fans spoke about how Snow's voice touched them personally: Poly Styrene came from a different school of music. The British singer, real name Marian Joan Elliott-Said, became famous for her stint leading the 1970s punk rock band X-Ray Specs, best known for the feminist anthem "Oh Bondage! Up Yours!." Her later music blended her punk sensibilities with a more modern electronic feel. She passed away after a battle with breast cancer on Monday evening.
