    IV IV
    McWhirter's music is music by a guitarist, for guitarists, representing the bond between a man and his instrument more so than focussing on compositional and orchestral concerns. Semi-spiritual and often meandering, SNDLPVN retains interest through some change of dynamics and orchestrations while keeping the music centered around the flowing guitar riffs.
  10. The Occident
    by Town Portal
    favorite track 00:00/00:00
    K. K.
    With what I would consider Town Portal's most fitting album art to date, "The Occident" is a distilled journey into cubist instrumental soundscapes. Utilizing a sound comparable to Dysrhythmia's, Town Portal eschew normal cantabile "leading melodies" in favor of a more pure focus on precise orchestration, bass melodies, grooves, and tight compositions. Because of this "The Occident" is not likely to get stuck in your head, but the listening experience is substantial and more than worth a listen.
  11. King Radio
    by Four Stroke Baron
    favorite track 00:00/00:00
    Great White Great White
    Four Stroke Baron straddles the barriers between straight-ahead heavy metal, art rock, and cinema, using a generous dose of saccharine (but satisfying) vocal melodies. This is the album many have been waiting for since the release of their EP, and I'm confident none of them are disappointed. Frankly I don't know any of the song names because the album flows so well.
