There's a significant difference between the two tracks, firstly in their length. "Changing the Timeline" spans a snappy 2:52 and it's in-your-face, more pure-grunge than the psychedelic, bluesy "Tidal Wave." A constant wailing guitar murmur, reverbed vocals and frenzied drums give this track an overall uneasiness.
The band worked with producer Liam Judson on this one, and given his track record (Belles Will Ring, Cloud Control) I'm not surprised that "Changing the Timeline" is yet another feather in the Laurels' cap.
Now already with two outstanding and diverse singles, Plains should be one of the most anticipated Australian albums of the year.
