Following the release of her debut EP, Strange Cacti, in 2010, Angel Olsen has continuously produced work that is moving, honest, and highly dynamic. Whether alone at the microphone or backed by a full band, Olsen traverses genre and expectation, creating timeless albums including the 2014 breakout Burn Your Fire For No Witness and last year’s masterwork, My Woman.

Slowly diverging from the lo-fi, sparse production of her early recordings, Olsen entered the realm of sonic experimentation seamlessly. Her songwriting is still at the helm, there’s just a few more effects in the mix.

Phases — a forthcoming (November 10) collection of B-sides and rarities — is a snapshot of each incarnation of the progression. Ahead of it’s release, we spoke with Olsen about her effects pedals, seeking out new gear, and her favorite guitar tones of all time.
