Tom Liwa (born Thomas Greiner, October 25, 1961) is a German singer-songwriter who has been performing as a solo artist in addition to being a founding member and frontman of the band Flowerpornoes. His artistic solo output long went unnoticed by German mainstream news sources and radio stations. In recent years, he has been receiving increased attention due both to a steady fan-base and various collaborations and contributions, e.g. to Klee's 2006 album Zwischen Himmel und Erde.
