Tomás Cotik's discography includes complete cycles by Bach, Telemann, Mozart, and Schubert, as well as his own arrangements of music by his countryman Astor Piazzolla. These releases have garnered him the highest acclaim from the best-known publications. Gramophone writes of the "joyful virtuosity and stylish musicianship that Tomás Cotik brought to [his] superb cycle of Schubert's violin-and-piano works," adding that these qualities "happily permeate [his] most rewarding Mozart cycle…. There are so many delightful details to savour that one hardly knows where to begin." Fanfare praises him, writing: "Cotik never indulges in violinistic brilliance at the expense of music, but he sounds consistently brilliant nevertheless." Dr. Cotik's thoughtful research on historical performance and his in-depth interpretations have repeatedly earned him favorable comparisons to some of the world's most famous musicians. MusicWeb International named his Schubert release a Recording of the Year, and his recording of Mozart's complete sonatas has six million Spotify streams. Cotik's Piazzolla CDs on Naxos were twice nominated for the International Classical Music Awards. Critics have described them as "among the very best" Piazzolla albums, as well as "exceptional… Piazzolla can be played differently than this, but probably not better" (DownBeat). Cotik's music and interviews have often been broadcast worldwide and in the US on American Public Media.
