Yusuke Morimoto's theme (starts at 4:18). I'm proud to say that this is the first SASUKE theme that I've ever identified immediately upon hearing it (i.e. without using music recognition software and/or searching soundtracks).
Doesn't seem like we can listen to the parts individually. Creative Music Assets is using soundcloud as a way to give potential clients a sampler of their works. Some seem to be complete pieces but the SASUKE one is only a highlight reel (hence the name): www.creativemusicassets.com/
