The Sims 3 Blues Jam Session (all instruments, all levels)
This is an audio playback of what the Blues jam session sounds like from the Sims 3 Late Night Expansion. All the instruments are present and the skills get progressively higher as you listen further. All instruments are balanced, meaning same skill level for each at that moment using the Book of Talent mod (a mod that allows for instantaneous skill [present and hidden] upgrades).
