Here's a very interesting demo from Greece. The band Echidna was formed in 2004 and though their biography is very poor (they only mention the participation in live shows) their debut demo is very interesting. First of all the package was very good with nice artwork (including the lyrics) - always a positive thing when a demo falls in my hands.
About the music. Their style is a mixture of death / thrash metal with many technical parts and several references in oriental themes (mostly on the guitar riffs). The vocals brought in mind Tom from Sodom, always of course with the usual Greek accent - but that's not a problem for me. The songs are quite lengthy in duration and it is more than obvious (especially after listening the demo several times) that the band has really given time upon the compositions. There are no boring moments in this CD, without becoming catchy or something relevant to that the band seems quite focused never letting the compositions stretch beyond the point of boredom.
One special notice goes to the excellent bass lines (something not so common on the genre). A better production would have definitely raised this to a whole different level but nether less the hard work of the band is striking from distance. I hope to hear more material from them soon.
