1. Ambrosius (Indie-rock band from Oslo, Norway)
Ambrosius is an indie-rock band from Oslo, Norway, active since 2015. Their sound blends 90s-inspired indie-rock with poetic lyrics, funky rhythms, synth-driven melodies, and genre excursions into blues, ska, funk, and disco.

They released four EPs between 2015 and 2021 before signing with rural label FAJo Music in 2023. Their debut album Pathways came out in January 2024 to critical acclaim from outlets like Earmilk. Their second album, Qualia, was released in August 2025, further expanding their genre-bending style.

2. Ambrosius (Alt-rock/conceptual band from Trondheim)

Ambrosius is a 9-member band from Trondheim, Norway, formed by students at the music program at Trondheim Cathedral School. Inspired by Kaizers Orchestra and theatrical rock storytelling, they embrace a “fun music” approach that spans genres like alt-rock, pop-punk, soul, and Latin pop.

Their debut single Fire and Ice was released in 2022. The band is known for conceptual live performances and participation in national stages like UKM. They have written and recorded their first full-length album.

3. Marvin Ambrosius (UK RnB Artist)

In a music landscape where authentic RnB artists are scarce, Marvin Ambrosius is emerging as a standout. Teaming up with independent label Praxis Records, he's crafting his debut album Marvelus—a dynamic blend of classic and contemporary RnB sounds.

As the younger brother of Marsha Ambrosius (formerly of Floetry), Marvin is no stranger to the music industry. He has written for artists like The Game, Nas, and Angie Stone, earning praise from figures such as Sterling Simms and Just Blaze.

With Marvelus, Marvin aims to fuse soulful roots with modern production, elevating the UK RnB scene and reaching a global audience.

⚠️ Not an artist: "Ambrosius" as hymn author

Some tracks—such as Come Thou Redeemer Of The Earth—are incorrectly attributed to an artist named "Ambrosius" due to metadata errors. These are choral works based on hymns written by St. Ambrose of Milan (c. 340–397 AD), typically performed by ensembles like the Benedictines of Mary, Queen of Apostles.

???? If you're here for a specific Ambrosius, please check album and track metadata carefully to ensure you're scrobbling the right one. Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
