Ricky Martin’s first Spanish-language album since 1998’s massive Vuelve salutes the Puerto Rican crooner’s roots while flaunting his pop savvy. The serpentine verses of “Jaleo” open up into a booming chorus; “Juramento” frames Martin’s voice in runaway drums and insistent strings. The ballads go all in, too: “Nadie Más Que Tú”, which Martin co-wrote, is awash in lush orchestration and gentle guitars; “Si Tú Te Vas”, penned by Colombian superstar Juanes, combines the breezy rhythms of mid-’00s soft pop with a soaring vocal.
