One word: Badass. If you play a stringed instrument this excerpt will have you reaching for your ax to play along. If you don't, you'll want to after hearing this. This excerpt features classic Beethovian c-minor in all it's glory. Including pyrotechnics! (check out the first violin part...)  

Beethoven String Quartet No. 4, Op. 18 No. 4, Mov I - Allegro ma non tanto

With 45 world premieres to its credit and 100+ concert works played throughout the United States, South America, and Europe, the iconoclastic Beo String Quartet does what it loves best: playing classical repertoire, contemporary, rock, and experimental music. From the Latin “to make happy,” Beo started out as a lark. Two Mexican-American brothers, Jason Neukom and Sean Neukom, decided to record a song entitled “Happy, Happy,” composed by Sean, but for that they would need two more players. And so in 2015 the Beo String Quartet was formed. Touring the world, composing, performing, recording, teaching, and having fun, Beo has since then founded Beo Publishing, built a recording studio, and started its own recording label, NeuKraft Records.
