Agora, Colonnelli, Aquefrigide, are all great pretty lesser known metal bands!
-Agora is a heavy metal band from Mexico, my personal favorite songs by them are Imperio, Víctima, Hombre Máquina, and Soy Veneno.
-Colonnelli is a sort of thrash/heavy metal band from Italy- my favorite band at the moment! Some good songs by them are Come Dio comanda, V.M. 18, Vi cacceremo senza pietà, Circo massacro, and Ero vestito di nero, plus they have a new album coming out soon :)
-No idea what Aquefrigide is considered, but they are from Italy as well. some good songs are Detesto, Anima, Trota, Fenis 6 Morto. In addition i’m pretty sure the artist Simona la Muta on spotify is the same person, i haven’t been able to find much information about them. Some good songs under that name are Dobermann, Ameba Bianca, and Larva!
Idk if you’d be interested in Colonnelli or Aquefrigide since i don’t know the exact genre, but I feel like you’d like Agora at least! :)
