Aviv Geffen (אביב גפן, born May 10, 1973) is an Israeli rock musician, singer, songwriter, producer, keyboardist and guitarist. He is the son of writer and poet Yehonatan Geffen and Nurit Makover (sister of Eli Makover), brother of Shira Geffen, and a graduate of Rimon School of Jazz and Contemporary Music. Geffen was extremely popular among Israeli youth, who were later known as the "Moonlight Children", in the 1990s. Politically, he associates with the Israeli left. His music contains subjects such as love and peace, but also death, suicide, the army, and refusal to serve. He is also controversial because of his decision not to serve in the IDF, though officially, he was dismissed for medical reasons. Early career Geffen's first appearance was in the film Hamitpahat (1987), for which he wrote and sang the song "Ima". In 1992, he played a part in the teenage television series A Matter of Time. That year, he also wrote a song for the Israeli movie The Beach Boys. Aviv performed in clubs with his band "The Mistakes (Hatauyot)" (the Hebrew name is purposefully misspelled in two places). He made his debut performance with "Cloudy Now" (Achshav Meunan), a song which later became his musical icon, and 12 years later was translated for the Blackfield project. In 1990, he recorded his first song, "Friend" (Chaver), together with the band "Cats in the Piping". In 1991, he released his first album, That's Only The Moonlight (Ze Rak Or Hayareach). All of its songs were written and the music composed by Geffen himself. Achshav Meunan was Geffen's second album, which was released in 1993 and reached Gold in the same year. It was produced by Moshe Levi and Ofer Meiri, who created a typical Geffen sound. Aviv expressed his generation's dissatisfaction with the government. The song "Cloudy Now" was followed by the question that many Israeli teenagers asked with Geffen - "Do you want change?"
