Gustavo Cerati is getting an emotional special…

National Geographic Latin America‘s TV network has released a poignant teaser for its upcoming docuseries episode about the Argentine singer-songwriter, composer and producer, considered one of the most important and influential figures of Ibero-American rock.

In the 30-second clip, the late Soda Stereo frontman sings “Happy Birthday” to his then baby son Benito in an archival home video shot by the Argentine musician himself.

The Cerati episode from Nat Geo’s BIOS series is due out in late fall for viewing in Latin America, according to a press release from the channel.

In the series, which is also set to include an episode about Argentine rock pioneer Charly Garcia, a participatory narrator follows the path of the subject’s life and career.

In this case, Chilean pop artist Javiera Mena will reveal the details about Cerati, through interviews with his children, Benito and Lisa; his former wife, Cecilia Amenábar, and others. The episode will show previously unseen footage.

September 4 will mark four years since Cerati died after having an aneurysm and going into a coma following a concert in 2010. As part of the now legendary Soda Stereo and with his subsequent solo career, he transcended his enormous popularity in Argentina to become one of the most influential artists that the Spanish-speaking world has known.

The two-hour documentary episode was directed by Sebastián Ortega, who is well-known in Argentina for his extensive work in television. “Gustavo Cerati is one of the greatest poets of our contemporary music,” Ortega said in the announcement from Nat Geo. “An artist with great sensitivity and unique inspiration who gave us some of the most original songs of Ibero-America of all time.”
