By next summer there will be a cumbia show at Hollywod Bowl. Mark my words.
I know cumbia clubs have existed for a while, so have their artists, but the above mentioned are not playing in exclusive cumbia spaces. They are playing to billingual Chicano/a crowds at local hip spots as well as Grand Performances. On the radio Jeremy Sole on KCRW drops a cumbia like he does at his weekly party, deep in the westside, Afro Funke. The beat is easy to catch, most anyone can dance to it and its plain fun.
Some Cumbia has an electronic element to it which is being played in tracks such as this one by Zizek
