Leading things off, 'Warning Signs' quickly indicates that the band is heading back to their roots, and not the same roots that led them to country and pop experiments. The roots are those first two Sub Pop albums, and this late-2000s indie rock vibe ends up on most of the record. Only 'Crutch' and 'In Need of Repair' sound like they are from a more recent era, leaning into a catchy indie pop/rock sound on the former and gentle strums on the latter. Lots of the other songs, including the opener and another single 'Lights,' get things to a really rocking place.
