At the age of 14, he began performing on stages across the country, playing original material and covers of his musical idols, such as Luis Alberto Spinetta, The Beatles, Jeff Buckley and Joan Manuel Serrat.

At the age of 18, while performing all over Israel and abroad, Lionel has been diagnosed with ulcerative colitis, a chronic intestinal disease which interrupted his life and forced him to take a break from stages.

During these years of absence from performing, he decided to begin teaching, passing along his accumulated knowledge in guitar playing, voice, composing and writing.

In 2008, after a long recovery, Lionel forms a band and starts a tour with his new songs and a growing audience, during which in one of his performances, he is discovered by the main editor of "The Voice", who invites him to participate in its first Israeli season.

In December 2015, Lionel released his debut EP in Spanish, his mother tongue, alongside a guest performance at Noa and Gil Dor's 25th anniversary concert at the Liceu in Barcelona.
