Armin Only is an all-night dance event featuring solo performance by Armin van Buuren. The event consists of various genres of electronic dance music (but most predominantly trance music), light, laser and firework shows and supporting acts of vocalists such as Nadia Ali, Racoon, Ilse de Lange, and Audrey Gallagher.

In 2008, in order to promote his album Imagine, a variation of the event called Armin Only: Imagine was introduced. This consisted of van Buuren mixing for 7+ hours with different events for each of the five senses- hearing, touch, sight, taste and smell.

In 2010, van Buuren began his "Armin Only: Mirage" tour to promote his album Mirage.

Armin van Buuren was born in Leiden, Netherlands on 25 December 1976, but grew up in Koudekerk aan den Rijn. Van Buuren started making music when he was 14.^{[citation needed]} He was inspired by French electronic music composer, Jean Michel Jarre, and wished to become a great electronic music composer like Jarre.^{[citation needed]}

He finished high school at the Stedelijk Gymnasium Leiden in 1995, and left for college to study law at Leiden University. While studying law, Van Buuren's interest for making music blossomed, and he began working as a DJ in a local club called Nexus. As his musical career began to take off, he put his law degree on hold, although he did return to finish law school in 2003.
