Reader Spotlight: Leandro Kalén

Leandro Kalén

While Leandro Kalén thinks in bass – thanks to his dad (also a bassist) – he covers a lot more ground. A multi-instrumentalist and producer, Leandro has performed with at least 50 acts in his 16 years playing bass.

Leandro is this week’s No Treble reader in the spotlight. Here’s his story…


I’ve played for 30 years and I’m dedicated to music as producer and performer. I was born in Buenos Aires, Argentina, and I began studing music at the age of 12.

Some of my studies and teachers: EMPA, Escuela Sónica, Gustavo Liamgot, Abel Rogantini, Rosario Bléfari, Roberto Catarineu, Osvaldo Fattoruso, Naná Vasconcelos, Rufus Reid, César Camargo Mariano.

After having participated in more than 40 albums, I’ve recorded a solo album, Mecánica Celeste, where incredible musicians colleagues were involved: Litto Nebbia, Michiel Bortslap, Jorge Cumbo, Hermeto Pascoal, Alambre González, Darío Sztajnszrajber, Juan Carlos Ingaramo, Jimmy Santos, Patricio Villarejo, Sami Abadi, Oscar Kreimer, Miriam García, Fernando Lerman, Rubén Carrasco, Juan Namuncurá, Pedro Menéndez, among others. On this album, I played the following instruments: glockenspiel, melodica, keyboards, synths, acoustic piano, 6/12 acoustic guitars, electric and synth guitar, percussion, soundscapes, voices, and obviously acoustic, fretless, and 4/5 electric basses.

I’ve interacted with, among others: Fuerza Bruta, Daniel Messina, Javier Calequi, Luvi Torres, Nicolás Ojeda, Baltasar Comotto, Raúl Carnota, Javier Barría, George Haslam, Paulo Alexandre Jorge…

Why I play the bass:

My father is a renowned bassist and teacher. That certainly has created a precedent for me. In every song I listened to, I could sing the bass part. At one point I found it terribly natural.

My bass superpower/claim to fame:

My emphasis is placed on the adaptation to different musical contexts. I’m interested in dialogue with the cultural baggage carried by each artist, especially through the language of improvisation. In fact, I would love to record with musicians from all over the world and connect with their ways of understanding music, through the benefits of new technologies.

I tend to think the music through the bass, but also I can play many other instruments.

My influences:

My first and main reference on bass is Sting. I’ve always been struck by his subtlety, finesse…that jazzy background, his powerful sound and dynamics for the benefit of the song!

However, there’s another bassist who will always be my devotion for many reasons: the immense Jaco.

Other major influences: Jeff Berlin, Oteil Burbridge, Eddie Gómez, John Patitucci, Derrick Hodge, Brian Bromberg, Ashton Barrett, Chris Squire, Mark Egan, Nathan East…
