Rubby Haddock's third concept album focuses on society and its aches and pains, all set around the story of one of Puerto Rico's most notorious fugitives, the late Toño Bicicleta. This LP (still obscure in many markets) was one of the most popular in the band's 22-year history, and, although the effort is rather rough as opposed to latter works, it is still poignant in terms of lyrical content -- one area that the band rarely touched afterwards. "Son los Nervios" was a highly popular merengue about particularly neurotic characters, and the rest of the repertoire features two different versions of the title tune. A must for record collectors, this recording is a modest sample of creativity in the salsa world, outside the powerful Fania empire. Vocals by Sergio Cariño.
