Awesome boss
Well this sounds like it would make an excellent boss song with the lyrics added in as well. Who was doing the singing here anyways? The song just has a great feel and reminds me of Dracula from Castlevania a whole lot too. Very well done piece too.
The vocals and lyrics are very great here. The guitar sounds really fast and quite awesome as I like it a lot too. The bass is groovy and quite well done. The drums are very cool and the double bass beat is great too and makes me happy to hear. I liked the use of synth here too making the beat all that much better.
The screaming vocals were awesome and the chorus/guitar breakdown sounded really nice while the synth in the background gives a soft feel to the beat in a good way, nice.
Overall, awesome Castlevania tribute piece I think.
