Rock was something of a musical revolution for Israel. However, unlike the rock music of America in the 1960s and 1970s, it was not always an expression of social revolution. Israeli rock, up until 1985, with the appearance of Aviv Gefen, almost never dealt with the themes of drugs, sex, youthful anger and alienation (though Arik Einstein's "Shuv Lo Shaket" is an exception), and revolution. Its stars, with the exception of Shalom Hanoch and Svika Pick, were clean-cut Israelis, mostly with neatly trimmed hair, who had served in the army and were exemplary citizens.
