Otto Benjamín de la Rocha López (23 August 1933 – 25 May 2020) was a Nicaraguan singer, songwriter and radio actor, best known for his characterization of the picaresque persona Aniceto Prieto.
Due to his work on the program "El Indio Filomeno" de la Rocha was sued on three occasions by the then head of National Guard radio and television Colonel Alberto Luna Solórzano.
De la Rocha maintained that the program did not express the names of figures from the then present era of repressive politics in Nicaragua.
He recalls that at Radio Corporación he, along with Carlos Mejía Godoy, ran a program called "Corporito" and The fine was for 10,000 córdobas ($1,428 USD at the time), which the populace helped to fund out of affection for the characters and actors.
His track "Una Canción" from the album of the same name was covered by Cuban singer Elsa Baeza in 1978 which gained her a golden disc in Spain; however, de la Rocha did not receive any recognition as the composer.
