Alex Bueno, the Dominican singer whose warm, unmistakable voice carried merengue and bachata into the romantic heart of Latin America, died on the morning of June 18, 2026, in New York City. He was 62.

Born Alejandro Wigberto Bueno López on September 6, 1963, in the mountain town of San José de las Matas, in the Dominican province of Santiago, he grew up in the highlands that would later lend him one of his most cherished nicknames, El Ruiseñor de la Sierra, the Nightingale of the Sierra. He found his calling early. As a teenager in 1978 he won a singing contest that opened the door to the world of professional music, and from there he made his way into the established ensembles of a country already devoted to its rhythms.

In the early 1980s he co-founded the Orquesta Liberación, a project that lifted his name beyond Dominican borders and announced a singer of rare tenderness. As Infobae noted in tracing his rise, Bueno helped shape a softer, more melodic strain of merengue, one built less on frenzy than on feeling. Over the decades that followed he recorded a remarkable catalog of more than fifty releases, moving with ease between merengue, bachata, salsa and bolero. Few singers in Dominican music could claim such range, and fewer still made it sound so effortless.

His songs became the soundtrack of ordinary life. Jardín Prohibido, Que Vuelva, Colegiala, Esa Pared, Amor Divino and Quién Te Riza el Pelo passed from the radio into weddings, kitchens and late-night gatherings, anthems of longing and devotion that listeners learned by heart and passed to their children. According to Diario Libre, these were the kinds of standards that endure across generations, the songs people reach for when words of their own fall short.

Though his roots lay in the Dominican Republic, Bueno spent more than a decade making New York City his home, where he became a living link to the homeland for a vast diaspora. He bridged eras as easily as he bridged genres, joining a younger generation of artists in a duet, Nuestro Amor, with the bachata superstar Romeo Santos, a meeting of the classic and the contemporary that delighted fans of both.

His death drew an outpouring from across the Dominican music world. The merengue singer Sergio Vargas remembered a friend as much as a colleague, writing, as reported by Acento, "Compartimos escenarios, canciones, anécdotas y momentos que guardaré para siempre en mi corazón." The group Los Hermanos Rosario hailed him as "un artista extraordinario, de calidad inmensa, con una voz irrepetible," while Milly Quezada, the Queen of Merengue, offered a tender farewell: "A cantar en la eternidad mientras acá te recordaremos cantando." The Dominican Academy of Artists and Entertainment Journalists called his passing an irreplaceable loss for the nation's music and for the artistic community at large.

Alex Bueno leaves behind a body of work that belongs not only to the Dominican Republic but to everyone who ever swayed to a slow merengue or hummed a bachata under their breath. His was a voice of consolation and romance, capable of dignifying heartbreak and lifting joy, and it will go on living wherever his recordings are played. In the towns of the Sierra where he was born and in the neighborhoods of New York where he made his home, the Nightingale falls silent, but the songs he gave away remain, carrying his tenderness forward to listeners who will know him only through the music. That is the truest measure of the legacy he leaves: a country that will keep singing him long after the final note.
