Onda sonora has arrived from inland, from an internal ocean; a warm and deep sea that does not appear on the maps. O SONORO MAXÍN brings with it the Cumbias that are not Cumbias, and awakens dances that have yet to be invented. They come full of rhythms that are out of time and that disjoint hips at the first beat, one-note harmonies and forgotten melodies that are found in the bellow of an accordion. Alongside them travel aphonic singers. Onda sonora reaches all ears in the same instant, in the twinkling of an eye, in new ways of measuring time; in a kiss, a hug, a smile, and to everyone with the same intention: to be heard.
