Calcutta, Nov. 16 :    Calcutta, Nov. 16:  Tobu Mone Rekho unfolding in a slowburning blues bias; Sankochero Bihavalata rising to a reggae bit; Birpurush interpreted as a rock opera, with a volley of violins, flutes and cellos forming an extravagant backdrop. Rabindrasangeet, that most Bengali of Bengali repertoires, is all set to go rock.VisvaBharati's copyright on the genre could well go by the yearend.And Bangla band Paras Pathar, in collaboration with recording label Asha Audio, is ready to take Tagore songs to the hithertouncharted area of .Rabindrarock.. . The idea is to give Rabindrasangeet a different sound texture without distorting the songs to reach out to a wider, relativelyyounger audience.Of course, the project can take off only if the copyright is lifted by December 31,. explains Mahua Lahiri, partner, Asha Audio and producer of the proposed album. Paras Pathar lead singer Ayan also promises there won.t be any distortion of the original Tagore numbers. .The notations will remain the same and the rhythm intact. Only the arrangements will be different, perhaps more complex, and we can bring in western elements like rock, reggae, blues and jazz,while sticking to acoustic mode.. Besides the regular set of leadbassdrumspercussionflutekeyboard, the band plans to use a string ensemble of 10 violins and cellos in numbers like Birpurush and Debatar Grash. .We want to give these a powerpacked timbre, something in the form of rockopera,. adds Ayan, admitting to 'strong influences. of The Who's Tommy and Jesus Christ Superstar. The production house promises to be .careful enough not to hurt sentiments...We are not venturing on this project as a cheap gimmick. It's a sincere effort to broaden the audience base for Rabindrasangeet.We know, commercially, it might be disastrous and purists might scoff at the idea,. says Lahiri. Some feathers are sure to be ruffled, but the listener will decide. .Everything depends on the audience.After all, they have been used to certain norms of rendition of Tagore all these years,. observes Rabindrasangeet exponent Subinoy Roy. Indranil Sen, one of the most successful among the present crop of Tagore singers, too, feels the audience will have the last word. .The people of Bengal are most profound in this repertoire and have a cultured ear for Tagore.However, I personally feel, if they are confident they can produce this album without distorting the originals, they should go ahead with the project and not wait for December 31,. says Sen.
