One word: incredible.
Over the past 10 years my standards for a good concert for any sort of "urban" music has deteriorated to almost nothing. Most live hip hop has become one famous guy and like six not famous guys rapping along to a song that sounds a lot better on the radio. If it were Rock Band, they would fail within the first five seconds.
I'm not sure who was the first to think: "this song will be better if some dude joins me on every fifth word. Oh yeah, we'll both yell to make it extra sweet."
Unfortunately, with strong influences of hip hop have leaked into Reggaeton and the few live performances I've seen have not been that great. Then, I saw Aventura at Madison Square Garden.
They sold the place out and I've never seen energy like this at a concert. They are talented, incredible, and work the crowd into a frenzy.
This video is a must watch for anyone who likes music and/or has a soul. Truly incredible, life changing stuff here.
In addition, they also provide this video which lets you know the massive talent gap between the Kings of Bachata and Wisin y Yandel.
