Singer U Sung Eun (also known as Yoo Sung Eun) held a guerrilla concert at COEX Plaza in Seoul on August 1. The performance was held to celebrate the upcoming release of her new track, "Marijuana." Over 400 people gathered to see her live performance.

She opened the concert by surprising the audience with her powerful vocals through tracks "Stay like This" and "Take Me Home." Before singing her new track "Marijuana," she explained, "I know the title is a bit provocative, but it's a track that reflects sincere feelings toward love. I hope you enjoy it."

"Marijuana" is a sexy blues track about a couple's love for each other. Those who heard her track at the concert prasied U Sung Eun's voice as "addicting, like a drug."

"Marijuana" will be released at noon on August 4.
