Days after the Jan. 12 earthquake that devastated Haiti, Latin music acts responded with an outpouring of generosity that the genre had never seen before.

Artists pledged money to rebuild orphanages, schools, hospitals and homes. They recorded public service announcements to solicit charitable donations, hosted concerts and wrote songs for Haiti. Several labels released singles and albums, donating the proceeds to recovery efforts.

Univision Communications aired the five-hour telethon "Unidos por Haiti" featuring performances from some of the top names in Latin music, and raised $8 million. And many of the genre's biggest stars came together to record "Somos el Mundo," a Spanish-language version of "We Are the World," to benefit Haitian charities.

Little more than a month later, another destructive quake hit the region, this time in Chile. While the quake was stronger than Haiti's, the resulting destruction fortunately didn't come close to approaching the scale of the national catastrophe that has ravaged the impoverished Caribbean nation.

Still, the subdued response of the Latin music community to the tragedy in Chile was striking, given the country's importance as a touring market for Latin artists. Indeed, the quake struck on the final day of Chile's weeklong Viña del Mar music festival, the largest and longest-running music fest in Latin America. And yet, there were nowhere near the same number of grand pronouncements by artists to assist relief efforts.

The reserved response of Latin artists to what's happened in Chile suggests that they're still learning their roles as public philanthropists.
