With plenty of hardship to sing about, this cowboy-hatted singer infuses tradition with the ecstatic energy of youthful rebellion. Valenzuela is a virtuoso accordionist who also plays drums and guitar; his productions vibrate with nuanced arrangements and percussive emphasis. But his well-cultivated, slightly dangerous image belies a sensitive touch: His seductive vocals pack emotion into every narrative corrido. “El Remmy,” as he's affectionately known, can also raise his voice in a classic ranchera glissando yell that's tinged with the pain of the lovelorn, yearning for caresses.
