He began his career as a lead vocalist and guitarist of Filipino alternative rock band Hale.

Lui Pio is also the son of Bernardita Dolino and musician Arturo Lui-Pio, also known as Nonoy Tan of the 1980s band Wadab.

Raised in the Iglesia ni Cristo faith, he converted to Roman Catholicism when he got engaged to his girlfriend, Claire Nery.

Other musical acts eventually signed up for Treehouse Productions to help achieve the band's purpose and objectives.

This development came after Arthur himself announced his intention to start a solo music career and as an actor.
