Sidechaining is very common (more of a law;) in House and Trance Music.
It is used to make more "pump" and a bit of a swing in the music.
Often used with kickdrum and bass, when you want to avoid the low frequencies of drum and bass to collide.
However, used in other music as well.
Listen to Avicii or Swedish House Mafia, use it a lot;)

Truthfully...I do not understand the concept of sidechaining.
Can someone point me to how, why and where and when to use it? ...or maybe point me to a good source of info on it? Thanks!
