have a look out for Clutch, (if you have not come across them before, - they have been mentioned on here)- they have been around for years but still are under the radar, - saw them last year as support for Thin Lizzy, - bloody brilliant. http://youtu.be/kx6FV2qR2TY
Perhaps also have a dig around this little website and look at few films:
