In this eighth recording, Willie Colon continues to bank on his "gangster" image, this time showcasing an illustration on the cover where the young bandleader from the Bronx is on trial. Colon stretches his wings by mixing genres of Brazilian samba into son-montuno, Afro-Cuban religious rhythms and Puerto Rican bomba and danza all showcasing lead singer Hector LaVoe's vocals. Colon's mature musical vision outpaces his young years and developing skills.
