Any Bangla Band Concerts Scheduled In Kolkata in the comin weeks?

Hello Beautiful Ladies,
I will be going to Kolkata with my friends very soon. Though they are Non-resident Bengalees, they are huge fans of Bengali bands, courtesy to me…lol!!!! I wanna take them to some concerts or show of our Bangla band, be it of any band…but I dunno if there are any such shows or concerts that are scheduled right not…if any of you know about any Bengali band concerts or shows scheduled in a fortnight from now then, please lemme know. Details like where to get the ticket and all are also required. I am sure you all will help me…
I will be waiting…
Bye,
Take care,
Shreya
