At fifty-eight, Gustavo Sánchez Haase has been active in the Paraguayan music scene for more than three decades. As a guitarist in Matasanos Del Rock, rock-band formed in the eighties hat after a break period they met again in 2021 and recorded the album "Tiempo Dificil". In 1989, while watching a live broadcast of a The Rolling Stones gig, he saw a guest appear onstage who was introduced to the audience as John Lee Hooker. That performance changed the life of Gustavo Sanchez Haase and the blues became his obsession. Currently his attention is centered between the Argentine combo La Posadas Jug Band and their staging as a one-man-band. Mississippi Blues, Hill Country Blues and Primitive Rock & Roll, that's his DNA.
