Brazilian music is famous worldwide — from bossa nova, to choro, to samba.
Bossa is cool, choro is amazing, but my favorite things about samba is that despite being "pop music" it still has complex rhythms and harmonies.
My top favorite thing is the prevalence of the 7 stringed guitar and their use of counterpoints (i.e., parallel melodies).
I love how what (I think) started as guitarists just playing harmonies, turned into them improvising bass lines and counterpoints every once in a while, which eventually became them doing MOSTLY counterpoints and bass lines and barely playing the harmony lmao.
These bass lines and counterpoints, from what I understand, are often times arpeggiations of the chords and so forth, but they add such an amazing effect to the music.
Examples:
- This guy solo playing over a recording.
- This solo guitar + singer.
- Most music by Cartola which features the absolute timeless 7 stringed legend Dino. This one is a classic.
Technical Death Metal. Depending of the band you get this ridiculously crazy and sophisticated instrumentalism and polyrhythmic beats like Archspire, other times you get more progressive, experimental groups like Blood Incantation that mix and match genres and soundscapes.
In fact, the newest album from Blood Incantation is a good example of that, one moment you're listening to fast blast beats and then it suddenly takes a hard turn into pink floyd and slowly starts crescendoing back into fast Death Metal over the next couple of minutes. It's an absurd aural experience to say the least, but I really like experimental music that pushes boundaries even when it doesn't totally work.
