HAIM have released a surprise expanded version of Women In Music, Pt. III, which features new versions of 'Gasoline', featuring Taylor Swift, and '3AM', featuring Thundercat.

The siblings teased a collaboration with Taylor Swift earlier this week, before fans spotted that Swift was credited on an alternate version of the track on the American Society of Composers, Authors and Publishers website. Artists frequently use the service to register their tracks for royalty payments.

The new rendition of the song comes from a longer version of their Grammy-nominated album. The record also features jazz fusion pioneer Thundercat.

In a review of the original album, Hot Press writer Ingrid Angulo called Women In Music, Pt. III "their best work yet", and said "it offers a clear evolution in sound, moving away from the pop influences on their last record to something edgier and ultimately more earnest."
