Lee Jung Hyun is a Korean pop singer and actress under Pine Tree Entertainment. She is widely known as "The Techno Warrior" or "The Techno Queen", but due to other singers singing Techno, she changed her title to "The Queen of Transformation". Her English name is Ava and her Japanese name is Hyony.
She made her movie debut at the age of 16 in A Petal, which won domestic and foreign film awards.
Before releasing her first solo music she featured as a guest vocalist on the Jo PD single "Fever", also appearing in the music video. She also appeared in the music video for Goofy’s "The Rule of the Game".
Lee assumes a unique persona for each album, such as a mermaid, Barbie doll, tribal queen, soldier, Korean folk dancer, belly dancer, or princess of the sea. She has garnered many nicknames over the years, including Techno Queen of Korea, Ms. Charisma, Little Giant, and Queen of Change.
Her early work is techno-style dance music. Her first single, Wa (와, "Come") topped the Korean charts for three weeks, while her second, Bakkwo (바꿔, "Change") won awards for Best Song and Most Broadcast Song. These two songs in particular were covered by artists throughout Asia and Europe. Many of her earlier songs are sung in an angry mood, from the perspective of a rejected lover.
Lee Jung Hyun released Japanese versions of her early hits Wa and Heaven in December 2004. The single ranked #26 on Oricon chart in Week 3 of January 2005. Heaven was a theme song for the Korean drama Beautiful Days. The drama became widely popular in Japan. On December 31, 2004, Lee was invited to perform Heaven and Wa-come on- and participate at the 55th edition of Kōhaku Uta Gassen, an annual New Year’s Eve live music show. In 2006, she released her first Japanese album, This is Hyony. The Japanese version of "Wa" hit #1 on Oricon chart in January 2005. Her Japanese fanclub was called Honey Hyony.

In May 2009, she released her first Korean mini album, featuring the title song "Crazy." The music video was choreographed by Brian Friedman.

She prepared an over-20-minutes-long special performance of her hits ‘Michyeo’, ‘Ban’, ‘Ari Ari’ ‘Wa’ etc., and including ‘Vogue It Girl’, and ‘Crazy’, with the companion of 20 back up dancers. Because Lee was personally invited as the guest opening performance, she has not only prepared her own stage, the two sang a duet together for the performance.
