Query: Pedro Conga brings new energy to Salsa

Pedro Conga definitely is one of the most talented salseros lately. He has joined an amazing leader singer: Maelo Ruiz, who has a powerful voice. Check the follow songs out: Noche de Mar, which probably is my favourite because of its executions, showing Maelo's voice quality. The other amazing song is Amor de Cristal, where Axel Martínez (chorus) makes good tandem with Maelo. Pedro Conga descarga on the conga showing up the reason why he is called "Conga". A must have CD for salseros who love dancing and enjoyng very fast and powerful songs.
