Guillermo Zarba is an exceptional pianist, with a solid academic background and a deep knowledge and love for folklore and folk-influenced music. In his album "Presagiado," he manages to find the perfect balance between popularity and academia, merging influences from Litoral music, tango, milonga, and other popular South American genres with skill and sensitivity. Zarba's instrumental compositions, predominantly chamamé, chamarritas, and milongas, showcase a wide variety in orchestration, with an acoustic sound that highlights the richness and musical texture. Although Zarba's piano guides the music, it would be simplistic to categorize this album solely as a chamamé or pianist's album. Zarba's compositions are versatile and rich in orchestration, with a range of colors and sounds that reflect his talent as a composer.
