Deletion of Calcutta Blues

Comment: Existing |RS coverage provided or that I could find is too faint to demonstrate notability. Band is very young, so could demonstrate notability in future. If anyone can find better sourcing (RS, and not trivial mentions), am happy to look again. Note to others searching: beware false positives to Dave Brubeck song of the same name, which has been covered by Clapton and others
