My Dreamgirl Don't Exist is one of my favourite songs. There are sites all about that host alot of the rare demos and whatnot, and some higher quality live recordings from NMH and Jeff Magnum shows, you should check them out. Holland 1945 is a close second favourite.
If anyone still cares about this thread, i found an artist you should defiantly check out if you like NMH. It's Jordaan Mason and the Horse Museum. They are a lot darker than NMH but have a similar lyrical style as Jeff and use a lot of instrumentation as well. defiantly worth checking out.
