Use your iPhone!
This was the band featured by Jeanne Moss in CNN (subsequently picked up by ANC). Very creative group of guys. And very catchy song, actually.
I don't know what app they were using but if you've been a long-time Mac user like me, you know that each Macbook comes with a Garage Band app that enables you to create your own songs, and play musical instruments therein. You can also record the same after and turn your songs into mp3's.
According to Jeanne Moss, Apple has already been in touch w/ Atomic Tom's record label to discuss some future projects. Coolness. Oh yeah, that guy playing the "guitar" is unmistakeably Pinoy. Woo-hoo! ;p
