Skay Beilinson started playing the guitar when he was 12 years old, his teacher was Leopoldo Ezcurra. In 1968, played with his brother in Diplodocum Red & Brown, and then in La Cofradia de la Flor Solar to the early 1970s, together with Kubero Diaz.
During the decade of the 1970s and early 1980s, was leader and guitarist of the band Taxi Rural and then was member from "La Galletita" with Edelmiro Molinari, with who recorded one full LP in 1982, through Microfon label.
In 1978, with Carlos "Indio" Solari and Carmen "Poly" Castro formed "Patricio Rey y sus Redonditos de Ricota" that established him as the core musician in the group. The band managed to be among the most important exponents of 1980s Argentine rock with Sumo, Virus, Soda Stereo, Charly García, among others.
By the 1990s, Patricio Rey became one of the most famous bands in Argentina. It became the band's mainstream success with La Mosca y la Sopa, Lobo Suelto - Cordero Atado and Luzbelito. Also, the band began to travel to Tandil and Junín stadiums to play their shows, increasing the audience.
In 1997, Skay, Poly and Indio were the only band members who had been in all their formations, and therefore decided to take more control over the band's future decisions, until Indio decided split Patricio Rey in 2001, for a while due to creative differences with the musicians.
Skay started playing as solo artist in 2002, and published his first solo album A través del Mar de los Sargazos. In 2004, published Talismán. After that, published his third album La marca de Caín, with the name of "Skay y los Seguidores de la Diosa Kali". In 2010, they published their fourth album ¿Dónde Vas?.
In August 2013, Skay together with his now-called band "Los Fakires" released La Luna Hueca, with Oscar Reyna as rhythm guitar, Claudio Quartero on bass, Javier Lecumberry on keyboards and "Topo" Espíndola as drummer.
In late 2013, Beilinson rejected a proposal of his former bandmate Indio Solari to meet with other members of Los Redondos.
