(Las Vegas, NV)  –  Carlos Santana kicks off his two-year gig on the Las Vegas Strip tonight.  Officials with the House of Blues at Mandalay Bay have spent half-a-million dollars to revamp the 13-year-old venue.  There are fewer seats for a more intimate feel, new furniture and an improved sound system.  You can even buy a $16 “Supernatural Margarita” in honor of the club’s resident talent.  Santana had spent two years at the Hard Rock Hotel before moving to the House of Blues.  Ticket prices start at $90.
