Nice combo !
This is in fact a very interesting piece. I must say I think you achieved your goal. Although, some transitions still feel like forced the music fits nicely. The guitar solos are what makes this music live. I do have to criticize the ending however. Your music should end at the 4min mark ... Somehow you decide to abruptly add a new set of drums (which feels like forced IMO) with the guitar. I believe you could have done it sooner.
Either way, nice work.
This deserves to be in front page. I wonder if I should search the rest of your audio repository :P
