String Quartet no. 3 in E flat minor, op. 30

The String Quartet No. 3 in E♭ minor, Op. 30, by Pyotr Ilyich Tchaikovsky, was composed in 1876, and is the last of his three string quartets. It was written as a memorial for Ferdinand Laub. (The date upon the manuscript is early February 1876.)
The quartet was performed for the first time at a party at Nikolai Rubinstein's apartment on March 2, 1876. The first public performance was at a concert on 30 March (new style/March 18 (old style), the performers being: Jan Hřímalý and Adolph Brodsky, violins; Yuly Gerber, viola; and Wilhelm Fitzenhagen, cello.
Once, while Tchaikovsky was staying with some friends, they surprised him by bringing in a string quartet who performed this quartet for him. When they finished playing, Tchaikovsky remarked, "At first I didn't much like the Finale, but now I see that it is quite good."
Recently, it was featured in the downloadable content Left Behind for the 2013 video game The Last of Us.
