Nancy Alonso was born and raised in Brooklyn, New York of Puerto Rican parents. Nancy grew up in the New York Salsa era and witnessed history in the making. She saw all the famous singers and musicians, danced to their music and even danced with Tito Puente when she was 12.

She moved to the Washington D.C. area in the 1980's. Nancy co-owned and operated a mobile DJ service known as "The Dynamic Duo DJ's". Her skill and expertise as a music programmer allowed her to crack into the professional DJ boys club. Nancy was given the stage name DJ ISIS (I Spin In Style) and made dance club history in DC. As DJ ISIS, Nancy played in some of the DC area’s popular and exclusive clubs including Numbers, Chicago, The Georgetown Library, Anastasia's and The Pisces Club.

In the late 80’s she turned her attention to Salsa. Nancy brought her knowledge of classic salsa and blended it with contemporary music. Nancy debuted at several area clubs including South Beach and Chelsea's and gained popularity among musicians and latin music lovers. In 1992 she made her mark at “Havana Café” where she was given artistic license to play hard core Salsa and Cuban music. Havana Café became the hot spot for Latin music in the DC area and was the inspiration for today’s salsa scene in the Washington metropolitan area.

Nancy went on to become host of the Monday night "Latin Flavor" show on WPFW 89.3 FM (www.wpfw.org) in May of 1999. Alonso's format concentrates on 1970’s classic salsa as well as Latin jazz and groups whose repertoire of music more closely represents Afro-Cuban rhythms and New York-style salsa. She also features local musicians and conducts interviews whenever musicians come to the Washington area from New York, Puerto Rico, Los Angeles, Miami and elsewhere.

Nancy is active as a DJ, a speaker at Hispanic Heritage Month events and as an MC for special events throughout the DC metropolitan area including the Smithsonian Institute's Jazz Cafe.
