Kacey Musgraves says she was on LSD listening to Bach when she came up with the idea for her new album 'Star-crossed'

• Kacey Musgraves fourth album "star-crossed" debuts on Friday.
• A guided LSD trip inspired the album, said Musgraves.
• The "Golden Hour" singer heard a melancholy Bach song during her trip and it led to the album's tragedy theme.

Kacey Musgraves' fourth album "star-crossed" debuts tomorrow, and the country singer said fans can expect a psychedelic-inspired track list thanks to a recent LSD trip she had.

During an interview on the podcast A Slight Change of Plans, Musgraves told host Dr. Maya Shankar a guided LSD experience largely influenced the writing and sound of "star-crossed."

LSD, also known as "acid," is a synthetic psychedelic that can cause altered sounds, colors, a happier mood, flashbacks, and increased heart rate.

Musgraves said she listened to a curated playlist during her psychedelic trip, which included music from Bach, the Beatles, and shamanic chants.

"The music I heard, I've never heard music like that in my life. You feel it in your bones, your cells. It's running through you in a way that I've never experienced before," Musgraves told Shankar, adding that she felt gratitude and warmth as she came down from her trip.

Musgraves isn't the first artist to say psychedelics influenced their music. Lorde recently told Vogue she created her latest album "Solar Power" while on MDMA, otherwise known as molly or ecstasy.

For Musgraves, a Bach song stuck with her the most and she noticed herself replaying it.

"It was this sorrowful, tragic number. The word 'tragedy' popped in my head, it was like 'Boom!' I was like, 'Wait, what if the new album is formulated like a modern tragedy?' It's a modern tragedy. I've been through a tragedy and so has America," Musgraves said.

Musgraves has promoted "star-crossed" as a modern tragedy in three parts. It's accompanied with a film starring Musgraves, which premiered on Thursday.

In an interview with Apple Music, Musgraves said "star-crossed" chronicles the end of her marriage and divorce from Ruston Kelley.
