Topic: Possible? Custom index and gallery?

What I would like to do is have a custom index that can show multiple galleries ... I know this is a little ambiguous so here's my example.

I shoot a number of different bands so what I would like to do is have a link on my site

// bands

which links to an index of different galleries for each band.  Is there a simple way to do this?  Should I just have multiple svmanager's installed in all the directories I want to have multiple galleries for a project?  I.e., bands, flowers vs bugs, portraits vs landscape, etc
