On Philippine rock band Siakol's ...Sa Pag-Ikot Ng Mundo (In the Rotation of the World), the music is gritty but also has melody. The band's sound is propelled by strong, reverb-edged rhythm guitar and also features searing guitar solos. The singing of vocalist Noel Palomo, who is also the group's songwriter, is heartfelt and gritty. Much of Siakol's sound is centered on the reverb-edged riffs and chord progressions purveyed by the guitarist, Miniong Cervantes, who often lays down a mighty path.
The band's music has an unpolished garage sound, giving it a stamp of authenticity. The opening song, "Habang Ang Lahat," begins on a heavy metal, Black Sabbath-styled path but then segues into a melodic, near pop-styled tune. Before long, though, the rough-edged guitar returns. "Sa Pag-Ikot Ng Mundo" (In the Rotation of the World) and "Yakap" (Hug) feature a spirited, flowing feel that is propelled by strong rhythm guitar. The rhythm guitar on "Sa Pag-Ikot Ng Mundo" also has a jingle-jangle ambience. The lumbering "Wag Mong Isipin 'Yon" (Don't Think) is far too long. The fine "Ayoko Na Sa 'Yo" (I Don't Like You Anymore) works off a hypnotic guitar riff, and the vocals achieve a strong anthemic stance. Because many songs on this album are centered on reverb-edged guitar work, the inclusion of more tender, acoustic-based songs would provide needed contrast. Stronger melodies throughout the album would also help.
