Bizarrely, there seems to be *another* band called lithium (http://www.jamendo.com/en/album/561/ - pretty good by the way). Or maybe this is the early demo tape version before he formed Lithium and his music changed a bit and became much tighter. In any case, it is very confusing.
His pieces certainly sound raw. Raw is good, usually, but here the mix does come across as annoyingly bad, with an over-emphasis on the voice. That I can overlook, but what really gets me is that when he goes into guitar-wank mode - the timing sometimes goes uglifyingly out of sync. Still, we've all done that when starting, and anyway, if you push yourself, you improve, and hell, at times it even sounds ok, so I'll even forgive him that.
He labels his stuff punk - maybe it's an attempt to cover the fact his playing is still so raw - traditional punk often had people who were barely musical. It's not punk really - it's plain old guitar rock. Not that it really matters, but just so people know what they'll be listening to if they pick this up.
On the plus side, the musical ideas he has are fine. It is just that polished versions of these would be such a vast improvement. So he needs to really listen to the sounds he's making with fresh ears, and improve his skill at making music. A tip, for what it is worth: playing with other guys, bouncing off ideas will dramatically improve his skills and sense of musical timing.
