La T & La M (La T y La M in Spanish) is an Argentine cumbia duo, made up of Tobías Medrano and Matías Rapen.
It originates from a pandemic, during the 2020 quarantine, when Tobías and Matías met in Florencio Varela, Buenos Aires.

Tobías, living in Varela with his mother and brother, was dedicated to uploading songs to YouTube, that's where Matías found him and quoted him in his recording studio "Tute Records" on August 27, 2020, so that together they could record a hooked as he used to do with various zone singers

The repercussion of the video was so great, the good comments and the good relationship that was generated between them instantly that they decided to start this band that we know today as "La T y la M".

After the restrictions due to the global Covid-19 pandemic were lifted in a large part of the country; they began their live presentations and were able to meet that audience that was so eager to see them.
