One of my first Playstation games, this is a great Steeet Fighter game and fighting game in general. The soundtrack is great, energetic and original: later Street Fighter EX OSTs don't come close to this one.
You can find a YouTube playlist with the songs here.
This OST is full of great tracks and mostly comprised of real instruments, which adds a raw, explosive energy ideal for a fighting game. Added keyboard melodies complete it by adding that game-soundtrack feeling.
There's some great guitar and drum soloing going on in fast paced songs: for example, listen to the mid-part (starting at 1:20) of 'Stronger' for a great drumsolo followed up by some Metal worthy guitar shredding.
The track 'Strange Sunset' starts of with a light jazzy piano melody, before epically going into overdrive around the 1 minute mark.
The 'Guardian of Light' track is a wonderful grooving track, with a nice guitar solo around 2:25.
