## Key points

- Sigh’s “Unputenpu” is Consequence’s Heavy Song of the Week.
- The song shifts Sigh towards melodic folk metal.
- Opeth’s Mikael Åkerfeldt contributes a guest guitar solo.

## Summary

Consequence has named Sigh’s new single “Unputenpu” its Heavy Song of the Week, praising the Japanese band’s move towards a more melodic folk-metal sound. The article argues that the track is unusually accessible for Sigh while retaining the theatrical, unconventional character developed across its long career.

“Unputenpu” features a guest guitar solo from Opeth’s Mikael Åkerfeldt, whose harmonised traditional-metal style is compared with UFO and Scorpions rather than his usual approach. Sigh began as a black-metal band and later became known for progressive, avant-garde music; the single is presented as a promising introduction to its forthcoming album, *Goh-Ka*.
