Although a couple guys, this act knows how to fill out a song in true rock band style. For instance, "The Bullet Train" features an extended electric guitar solo, which doesn't ever sound excessive. In contrast, "Petals," with its soft keyboard part, tamps the music down to a gentler, jazzier feel. In other words, The Soft Underground knows how to gear down when need-be. And is that real flute on "Voicoder," a moody, exotic little number? "Thank You" features a female lead vocal, which lends even another color to the project's overall expansive palette.
