I don' t know if anyone else has heard of this band but Rodrigo y Gabriela, an acoustic guitar duo from Mexico City, is in my opinion one of the most talented flamenco groups out there right now. Rodrigo Sanchez (lead guitar) and Gabriela Quintero (rythem guitar) started out playing heavy metal music in Mexico City but then relocated to Dublin, Ireland and switched to acoustic/flamenco music. They have recently released their second album, 11:11, and are beginning another tour.
I ranke these guys skill-wise with artists like Esteban and Eric Clapton when it comes to acoustic guitar. And their earlier heavy metal style playing is evident in their fast-paced playing and covers of Led Zeppelin's "Stairway to Heaven" and Metallica's "Orion." My personal favorite is "Satori." I would definately recommend Rodrigo y Gabriela to anyone who has ever been a fan of acoustic guitar. Here's a link to their website:
