Singer-composer Shankar Mahadevan, who will perform a live radio concert, finds it an interesting concept.His concert will be broadcast live on Radio City as part of "Gig City Season 2" on Friday."A live radio concert is a trend-setting concept. Performing live for an audience of 5.25 crore is an unheard of feat. I have sung in studios, live and even impromptu, but the idea of ‘Aap Jahan Concert Wahan' (Concert is wherever you go) is amazing," Shankar said in a statement.As part of the performance, Shankar of the Shankar-Ehsaan-Loy group will render folk songs that represent India.He describes it as My Country My Music - India's first world music folk act, and the songs have been hand-picked by him especially for Radio City's listeners.
