The book contains 12 songs by the Nicoyan artist and 12 others by another living legend in Guanacaste’s music: Guadalupe Urbina. That’s why they tried to make the songs included in the songbook reflect the rich variety of rhythms that exist in Max and Guadalupe’s songs. The recordings were made with support from the National University, and Javier and Óscar created the sheet music for each song, a difficult task because each one is composed orally and not written down.
