Pedro Flores born (March 9, 1894 – July 14, 1979) was one of Puerto Rico's best known composers of ballads and boleros.

When Flores began to have problems with the music publishing company, he made the decision to leave the trio.

[1][2] Flores composed various different works, including: Obsesión, Amor Perdido (Lost Love), Bajo un Palmar (Under A Palm Tree), Borracho no Vale (which may translate to Drunk Doesn't Count or Doesn't Count If You're Drunk), Linda, Sin Bandera (Without a Flag), Despedida (Farewell), and Perdón (I'm Sorry).

[1][2] Well known performers such as Beny More, Los Panchos, Celia Cruz, and María Luisa Landín collaborated with Flores in portraying his works.

A 1996 television special honoring his work features versions by many Puerto Rican and international artists as well, such as Ednita Nazario, Marc Anthony, Yolandita Monge and Shakira.
