Violin Concertos of the 20th century

Because there are simply so many valuable concertos for the violin in the history of music that one should not limit oneself to the generally known concertos. Whereby known and unknown are to be understood relatively, of course. Often, however, the discovery of the unknown can lead back to the known. Also in the history of violin concertos, "survival of the fittest" cannot be the criterion, but rather cooperation of the most diverse variants of possibilities in the service of the preservation of the species "violin concerto".
Thanks to Youtube it is possible to get access to unknown music at any time. To hear more unknown violin concertos in concert halls, however, would be phenomenal.

"Here is something that touches me deeply. What is it that echoes in me and makes me cry, how has the composer reached me and brought to light something that was buried in my soul? So we musicians have a cathartic task to lead many people in a concert to existential questions in a joyful but often also painful process and also through the process of healing." (Christian Tetzlaff, violinist)

"The 'creative triangle' - an image coined by Benjamin Britten - in which true music is created includes not only the composers, who invent a piece and write down the notes, and the performers, who rehearse these notes and bring them to life more or less adequately, but also the audience, who are prepared to listen to the music. Without an audience, there would be no music." (Eleonore Büning)
