The result was Keep. A google news search yields several relevant hits that can be used as sources for information. The articles there (including one by the Chicago Tribune) appear to be enough to establish notability. Malinaccier (talk) 03:01, 5 August 2009 (UTC)[reply]
This is one of those genre pages that has stuck around far longer than it rightfully should have. There's no factual evidence that this is an actual genre. Instead, it's just an assemblage of bands that use the cello instrument. The first AFD from two years ago passed as "Keep" with little comment and was based on the argument that "Hey, these bands all use cello!", which isn't good enough for our notability and original research guidelines.
