(upbeat electronic music) (Martin sings in Spanish) - My name is Martin Guas.

I am from Argentina.

And, I've been attending Berklee College of Music since 2017 'til 2020 and now working as a professor at the college.

(Martin sings in Spanish) - [Martin Guas] "Creo" was a song that I wrote a long time ago, that their melody remained in my head for a long time.

I never felt that the lyrics were right on point.

My high school times, every Friday, we had to go to church, and we used to say this, this prayer, called "Credo", which is, "I believe in God almighty".

So, I asked myself, why not write something that I believe in or people in the 21st century believe in?

(Martin sings in Spanish) - A big part of being a great performer or recording artist is having your own voice, your own authentic voice.

(Martin sings in Spanish with a soft piano melody) - [Daniel Cantor] Working with Martin is fun, and rewarding, and lovely.

Like, watching him grow as a student into a really solid producer, songwriter, (Martin sings in Spanish) you could see this nugget of just pure emotion in his creativity and, and his desire to tell a great story.

So I just watch through these three classes, as he got better and better as a producer, and someone who had better insight into how he could connect with his audience by performing better, and his vocals get better.

And, by the end, we were mixing, and, and balancing things, and creating moments that enhanced the story in his songs.

- [Martin Guas] I think I found a deep reason in an early age, and that made me... No matter whatever I had to do to pursue music, which, it was what I love.

I was born in 1991.

And I was raised in a music store, which my parents started working when I was four or five years old.

The environment and living around instruments made me find a lot of interest, and also, to understand music as a language.

When I was about 17, 18 years old, I decided to take music seriously.

I found a master.

He helped so much with piano, about understanding music in general.

I got the opportunity to audition for Berklee.

I think, coming here was one of the things that really changed my perspective of life.

(upbeat acoustic rock music) [Martin Guas] It was a big challenge to make the decision because I had a career in Argentina already, and coming here was to start over.

But, I did it then, and I think, it was the biggest and best decisions that I ever made.

(Martin sings in Spanish with upbeat acoustic rock music) ♪ Da-da da da da-da da da da ♪ ♪ Da-da da-da da-da da-da ♪ (Audience sings offscreen along with Martin's guitaring) Thank you very much!

(Audience claps and cheers) (Soft guitar melody) One day, I just decided to take a hard drive that I had with a lot of songs, I believe it was around 200 or more.

And I was very lost in my songwriting, and it felt like everything that I been writing for that time was not resonating with my artistry anymore.

So, I just, I just, took it, and I throw it in the river.

(Martin sings) (Intense guitar melody) Sometimes, like you just realize a certain truth for you are not truth anymore, and you move on.

(Martin sings in Spanish with soft guitar melody) (Martin sings in Spanish) I grew up listening to Prince, to Stevie Wonder, to Michael Jackson, to a lot of people that, I didn't what they were saying.

But at the same time, there was something in the music that was making me feel very interested about what they were trying saying to communicate, even though I wasn't understanding the, the language.

The way I compose depends on how things happen first.

(Martin sings in Spanish) Sometimes I will have a melody in my head that I'm whistling or having during the day, and I just come back home and then try to make it work with some lyrics and some chords.

Sometimes I have a chord progression.

(Soft piano melody) - Yeah, that's gorgeous.

- That's kind of like the idea of the- - Yeah, something that's beautiful.

- [Martin Guas] I do believe that better lyrics come out when you write the lyrics first.

(Martin sings in Spanish) I feel very comfortable with Spanish writing, and I'm really working on, on the English lyrics and learning because there is such a difference between the way we express metaphors.

(Martin sings in Spanish) What's happening right now in the world is crazy, that after a pandemic, we don't have the empathy to stop creating things like whatever's happening in Russia and Ukraine.

It's unbelievable that, as humanity, we continue to hurt, to destroy.

The idea with the video is just to show that, as humanity, we are closer to each other than when we think we are.
