(ROCK): Another masterpiece from the band, Problemas is a worthy follow-up to 2010’s Grammy-winning El Existential — as well as 2008’s Sonidos Gold. Yet, this Steve Berlin-produced album was somehow sitting around unreleased for a couple of years. Thankfully, it saw the light of day in 2015. Grupo Fantasma, known for their incendiary live shows, captures that spirit on this record while maintaining their nuanced arrangement and strong vocals. “Otono” shows the power and precision of the band with a cumbia feel, while “Porque” updates the Beatles’ “Because” in a delicate and inventive way.
