Callalily’s frontman Kean and Gracenote’s lead vocalist Eunice collaborate for this “Happy Together A Trip Down Memory Lane” to give a different twist to old time favorites. I must say that this album sounds like a Callalily’s album having a band on the background with a boy-girl vocals. I love OPM music but this album is not the sound that my ear is looking (hearing) for. Duets and solo performances of each songs are given different style and sound. I dont know if this album sold a lot of units but for me there are a lot of Pinoy album out there that is worth the money.
