Dawn of Tears - melodic death metal from Spain, sort of a cross between Dark Tranquillity and Kalmah. While not the most original sound, they do perform the style very well. Their debut album "Descent" is available for free download.

Demilich - abstract, technical death metal. They disbanded after releasing only one album, the untouchable "Nespithe". Their sound was far ahead of their time...bizarre, on the brink of total chaos. A complete mindtrip, I guarantee you have never heard a band like this. Antti Bowman's vocals have to be heard to be believed, though it's a matter of debate if they were altered during recording. You can download Nespithe along with other promos and demos at their website. And best thing is, it's available in FLAC!!!

End of Man - vicious thrash metal from my homeland. In the style of Anthrax and Forbidden, this will get your head banging. Joey de Guzman sings in the vein of Joey Belladonna, and the rest of the band is as tight as hell. Download their self-titled EP now!
