"Epic Intro 2015" is a solid entry point. The initial impact is strong, with a driving, pulsating synth rhythm that immediately grabs attention. The way the track builds intensity is well-executed, creating a sense of anticipation, and the breakdown at around 0:24 provides some nice dynamic variation, a needed moment of breath, before kicking back in.
From a compositional standpoint, there's good use of arpeggiated synths, adding a feeling of complexity and movement, that contributes to the track's overall energy. However, expanding harmonic elements in some parts of the piece would bring more value to the track as a whole.
On the production side, the mix is generally clean and the sounds are, for the most part, well-chosen for this style. It's got that modern, almost futuristic sound that's popular in a lot of media today. It's easy to hear where this could fit – action sequences, dramatic trailers, maybe even a video game menu. To elevate it further, a greater variety in percussive elements, or the addition of a more unique, signature sound element could really make it pop.
Overall, "Epic Intro 2015" delivers on its promise of being a high-energy, attention-grabbing piece. Some small refinements might enhance its emotional depth and uniqueness, but the track's overall effect is, indeed, positive.
