Lisandro Alfredo Arias Baro started his professional career at the age of 16, playing piano with a group called Los Caribenos, with whom he toured across Cuba. His aggressive style of playing montuno caught the attention of several top musical directors and in less than a year he had joined the Estrellas Cubanas orchestra.

By 1991 he was a member of La Banda Meteoro. He went on to perform in prominent shows (Cabaret Parisien, Tropicana and Noche Cubana) and prestigious musical formations (La Orquesta Reve, Costa Caliente, Los Diez de la Salsa, and Valentin y su Grupo).

In 1993, Lisandro took over the reins of Baroso, a group in which he played alongside his uncle Joseph Baro, his brother Igor Arias and Juan Carlos Formell. The group performed at the Boca Chica club in Cuba every Saturday for eight months.

At the same time, Lisandro was engaged in musical projects with musicians as varied as Junior Gonzalez, Juan Carlos Formell, Danny Rojo, Miles Pena (with whom he produced an album entitled Mis Ideas in 1997), Los Jovenes del Barrio, Net Sublette, Victor Manuel, Franckie Negron, Charlie Cruz, Ley Alejandro, DLG, Sergio George and Raulin Rosendo (for whom he composed and produced arrangements for a number of tracks).

He worked as musical director for Conjunto Los Soneros de Oriente, Donato Poveda, Siete Rayo (with Descemer Bueno), Conjunto Raices Habaneras (with David Oquendo), Magic Juan and La Orquesta Reve (US tour 1997-1998). And he played piano for Jose Alberto El Canario and Celia Cruz, the latter on two world tours that took him to Italy, Spain, Germany, Austria, Britain, Switzerland, Sweden, France, Colombia, Mexico, Venezuela, the Dominican Republic, New York, Miami, Boston, San Francisco and Los Angeles.

Today Lisandro heads his own ensemble, founded in Havana on 18 January 2001. As in all large changui orchestras, the group has a string section composed of three violins, and a horn section made up of three trombones, a flute and a saxophone. Lisandro y su Tratado has shared stages with Bamboleo, the Orquesta Reve y su Changui at the Benny More festival in Cienfuegos, and Manolito and su Trabuco at the Palermo cabaret in central Havana. Lisandro himself was invited by Cesar Pedroso, leader of Pupy y Los Que Son Son, to play a series of concerts across Havana, a collaboration that maestro Pupy characterised as "a meeting of a father and his spiritual son".

Lisandro's tirelessly creative approach to popular Cuban music has earned him the respect and admiration of audiences and salsa musicians alike. His street style, a combination of changui and Cuban songo, gives his music a unique and inimitable touch. Now based in New York, Lisandro y su Tratado are expected shortly to bring Cuba's new son to Europe, with a new album due out in 2009.
