During the '90s, Sergio George's trombone-heavy arrangements toughened up salsa romantica. Punchy tracks like "Te Conozco Bien" made Marc Anthony a star, and "La Negra Tiene Tumbao" reignited salsa queen Celia Cruz's career. His visionary instincts led him to mix songo, salsa, funk and hip-hop in the music of groups like DLG ("Juliana") and New York break-out bachata act Xtreme ("Te Extraño").
