I just have to pipe in here, as a HUGE Brazil and Bossa nova fan:

Brazil 65 - not 66! 66 was commercial pap in comparison.

First my personal story: As a lad of 14 or 15, I went to see the Smothers Brothers at the grand Masonic Auditorium in San Francisco. To my immense pleasure and surprise, the opening act was Sergio Mendes and Brazil 65! I'd never heard them before and my world was changed forever for the better. Great pianist Mendes, towering bass player Sebastaio Neto, amazing Paulinho on drums and percussion, and the most wonderful, sexy and fresh vocalist Wanda de Sah just opened up my world of music. The one and only Brazil 65 album is now on CD, and Wanda Sa has played in New York in the past few years. I don't know what became of Rosinha de Vaklencia, but she played the most exquisite nylon string guitar, better than Tom Jobim ever did...

Oh darn, there goes another evening, I'll be reveling and dancing the samba the rest of the night :-)
