From “The Firebird” to “The Rite of Spring,” Igor Stravinsky's classical pieces are some of the most iconic works of the past 100 years. But one of his compositions would sound unfamiliar to even the most devoted classical music lover alive today. That’s because following its first and only performance in 1909, the music was lost in the chaos of the Russian Revolution before being rediscovered in 2015. Now The New York Times reports that the second-ever concert of the piece will stream for free on Friday, December 2.

The 12-minute orchestral score, titled “Funeral Song,” was written by a 26-year-old Stravinksy in honor of his late teacher Nikolai Rimsky-Korsakov. Musical scholars believe the score might bridge the gap between his early works and the distinctive sound of his later ballets, one of which was so unsettling that it caused audience members to riot when it debuted.

After “Funeral Song” was performed at a memorial concert for Rimsky-Korsakov, it “unfortunately disappeared in Russia during the Revolution,” as Stravinsky wrote in Chronicle of My Life. Last year, the composition was uncovered from the St. Petersburg Conservatory. It will be performed by the Mariinsky Orchestra in St. Petersburg this Friday at 2 p.m, EST. Classical music fans can tune in on Facebook or medici.tv.
