Medtner's Primavera is the third piece in the Op. 39 cycle Forgotten Melodies II ("Vergessene Weisen"). It is subtitled "Frühlingsmärchen" (engl. Spring Tale) and was completed in March 1920 after the arrival of a beautiful Russian spring. It is the only piece in the cycle that doesn't share any thematic material with other Op. 39 works.
The music starts with a vivacious preamble that leads into the main theme (00:14). The theme is long, lyrical, and in contrast to the preceding pieces very diatonic. The music moves impatiently (01:41) from Bb to Cb for a tender middle section, its subject related to the first theme (01:52). After a recapitulation of the first section, this subject also joyously concludes the piece (03:17).
This is one of Medtner's unabashedly happy pieces, in stark contrast to the preceding two. What is interesting is that the first motive of the dark Op. 39/1, Meditazione, also appears in the beginning of Mednter's song "Winternacht" (engl. Winter Night, Op. 46/5), possibly associating Op 39/1 with winter. If we take the abstract, introverted character of the Meditazione into account, the following interpretation becomes possible: The Primavera may not only describe a literal spring, but also a rebirth of the soul, coming from the tormenting darkness to a new awakening. Medtner continues this imagery of new life and optimism in the following Canzona Matinata ("Morning Song"), before it is shattered in the Sonata Tragica.

Tozer's playing is simply amazing, not sacrificing a single ounce of lyricism to the piece's demand for speed and bravura.
