3DayTrial started out on Jan 2006, supposedly, as a Do As Infinity cover band. The band was founded by the original members: Neil Gamboa, Adi Yapyuco, Justine Yapyuco, Dek Yap, Alex Artillero and Aissa Guilatco.
This did not push through until mid-October. Prior to this, Neil Gamboa had left and was replaced with Jay Ambanta.
3DT's first gig was in Nihon Kenkyu Kai's Nihon Night in De La Salle University. Soon after, they have been performed in various events such as Ongaku Society's gigs and Hero's "Hataw Hanep Hero".
Currently, 3DT is comprised of band members:
- Adi Yapyuco (vocalist)
- Justine Yapyuco (bassist)
- Alex Artillero (drums)
- Dek Yap (guitarist)
- Aissa Guilatco (keyboardist)
Currently, 3DT is a cover band that specializes in japanese music.
