He's also the creator of a free urtext-style edition of the Koussevitzky Double Bass Concerto, based on a previously unknown personal score copy he discovered at the Library of Congress. We cover a wide range of topics: Isaac's years-long journey developing his handcrafted rosin (Winter), the unique acoustic challenges of the double bass that make rosin so stubbornly hard to get right, and his Library of Congress discovery of Koussevitzky's clean personal score\u2014complete with hidden measures taped over by the composer himself. We also dig into AI's expanding role in Isaac's tech projects, the ethics of open-source music tools, and the tension between building things because you can versus building things that actually matter.
