Coming from Darren Korb, the same genius that put together the Bastion OST, this is an absolute must listen to, part jazz, part electric hip-hop, all wondrous music, you owe it to yourself to give it a listen. I can't recommend one song. Listen to it all.
A beautiful addition to the Overclocked Remix label, TMNT Shell Shocked is one of a kind remixing all the magic from Turtles in Time and a bit from Hyperstone Heist. Its a wonderful hard rock re-imagining of the soundtrack filled with swanky bass. Stand out tune from me is Casiopizza vs. TMNT-Square (Night Riders [Stage 8 BGM])
Beautiful piano swells throughout this entire soundtrack. It is both sad and creepy and to tell the truth I am completely impressed by Óscar Araujo. While all of the classics we know and love from CastleVania are absent this soundtrack has a wonderful thematic singularity that runs throughout the whole OST. The instrumentation is beautiful and the strings and the horns never overstay their welcome. Listen to Dracula's Theme and you will get a taste of what you are in for.
