Before she was known for her three high notes in Good Day, IU was just a 15 year old girl with a powerful voice when she first debuted on MNet Countdown in 2008. Though her debut mini album was not commercially successful, you cannot deny she had plenty of potential as a singer back then.
The title track of her debut mini album was Lost Child (미아) which showcased her incredible vocals.
Personally I found the music video quite odd to say the least. Are they zombies? Dancing zombies? I'm not exactly sure. The music video featured her friend in the company, Park Sang Hyun, who would later debut as Thunder in the idol group MBLAQ in 2009.

Vocally she was impressive but her facial expressions seemed stiff. But I would credit that to nerves and inexperience to the stage.

A huge improvement from her performances back in 2008. A lot more emotionally expressive. Oh how IU has grown.
