Buddy Holly was genius, one of the first great singer-songwriters, an inspiration to the Beatles, the Stones, Dylan. “The music died” when the 22-year-old Texan perished in a tragic plane crash with Ritchie Valens and the Big Bopper on a snowy field in Clear Lake, Iowa, nearly 50 years ago… but the music really didn’t. Holly continues to be a driving force in rock ‘n roll, and with the anniversary of his death his work is showcased in two multi-disc sets: the three-disc “Memorial Collection” (an overview of his career) and the two-disc “Down The Line — Rarities.” On Feb. 2, Graham Nash, Los Lobos and others will gather at the legendary Surf Ballroom — the site of that final Winter Dance Party concert and and now an official Rock ‘n Roll Hall of Fame landmark — to pay tribute to Holly.
