The first movement is a milonga and the harmony twists and turns with the feeling of Latin jazz. This mood is broken when both parts lock into a synchronised tremolo section. Although it is a bit of a surprise when it breaks in, it provides an interesting contrast and is effective here. The reflective mood returns with a short section, full of emotion, leading beautifully into a cadenza, which is a solo for guitar one; nice touch.
Guitar two returns, as does the original theme. One more opportunity to play that beautiful tune again before the waltz in 6/8 dances in, creating a new mood which sweeps you away in another direction but maintains the quality of the writing of the Prelude. Diminished progressions add interest and tension as this section develops. The parts intertwine effectively throughout, sharing melody and harmony.

This piece demands a fluent technique from both players, although it is flexible enough to work at an easy tempo. There are so many instant rewards here that getting it under the fingers will not be a chore.

Highly recommended.
