Cazzette came out of left field with “Sleepless” — abandoning their brand of quirky dubhouse and releasing one of the most acclaimed crossover records of the year. Finding the venue to produce deep sounds with a commercial appeal, the duo find themselves sharing space with the likes of Oliver Heldens and Zhu; “Sleepless” made this positioning indisputable. And they’re not done yet. Following up their 2014 trademark wouldn’t be easy, but Cazzette make such effort seem like a cake-walk. Their latest is “Blind Heart,” a brave approach to electronic music that’s somewhere between its predecessor and David Guetta’s “Dangerous.” Vocalist Terri B brings soulful attitude that pairs well with the original percussion, making for a sound that couldn’t be more traditional, nor more modern, all at once. “Blind Heart” could quickly become a favorite throughout dance music as well as radio.
