The next phase of the rebetiko revival can be said to have started in the beginning of the 1970s, when LP reissues of 78 rpm recordings, both anthologies and records devoted to individual artists, began to appear in larger numbers. This phase of the revival was initially, and is still to a large extent, characterized by a desire to recapture the style of the original recordings, whereas the first phase tended to present old songs in the current musical idiom of Greek popular music, "laïki mousiki". Many singers emerged and became popular during this period. It was during the 1970s that the first work which aimed at popularizing rebetiko outside the Greek language sphere appeared and the first English-language academic work was completed.
