In 2001, Philippine rock band Sandwich released their second album, 4 Track Mind.

Four of the five members of Sandwich are members of other Philippine bands.

What began as a side project has become a viable project in itself, though the Sandwich members still belong to their original bands.

After an introductory rap called Feedback, the music starts on a strong note, as "Food for the Soul" opens on a repetitive, searing electric guitar line that leads into the roar of hard-edged chords, upon which the assorted vocalists launch into rambunctious rapping.

The song's sound is comparable to the rap-metal of such international bands as Limp Bizkit and Crazy Town.

"Ultrasound" opens on an enchanting chord progression, as the speed picks up and leads into hard-edged, punkish-styled guitar; heard then is the strum of a dreamy augmented chord followed by melodic singing.

The song takes various directions, but fits into a cohesive tapestry held together by melodic singing, some of which is heard in fragments.

Sandwich takes chances and explores various styles on this album.

"Hair Pin," for example, is a big switch in styles, as the song is acoustic in nature and the singing is tender.

"Too Far" is performed in a hard rock style and has a dissonant edge.

"Love Is" starts on dreamy electric guitar and an ethereal-sounding organ solo.

The song is also tender and dreamy.

Side two of the cassette also contains many songs with a dreamy edge, both hard rock and acoustic.

However, this tends to sound derivative, and the album begins to repeat itself, although the closing rocker, "4 Track Mind," has substance.

In addition, at 16 songs the album is too long, and would have more of an impact at ten or 11 songs.

Still, there is much to appreciate, especially on side one.
