For Ilana Besha, 19, the songs conjure up images of the first mass aliyah from famine-stricken Ethiopia to the Promised Land. "When word came to our village that we were going to Israel, it was like a dream come true," said the teenager, who was in Los Angeles last week with Shlomo Gronich and the Sheba Choir. But her long, exhausting journey was fraught with danger. As Besha, at 4, walked with her family across the Sudan, several of her baby cousins wasted away and died. "They are buried in the desert," she said.
