Here are some factoids on some of the artists:
Marcos and his brother Paul Sergio Valle are often termed the Gershwins of the bossa nova, being siblings and all, with Marcos writing the music and P.S. handling lyrics. You probably know their best-known song, "Summer Samba" (made famous by Brasilian organist Walter Wanderley) by heart.
Miucha is the second wife of Joao Gilberto, one of the founders of the Bossa Nova, and also the mother of current Bossa Nova superstar Bebel Gilberto. Miucha's brother is Chico Buarque, best known for "A Banda," which was a hit for Herb Alpert (though you should listen to the original Brasilian vocal version by Quarteto em Cy).
Bena Lobo is Edu Lobo's son. Edu is probably my favorite of the post-Jobim composers, and has so many gorgeous songs to his credit it's impossible to list just a few. Tomovoz of course will know that Edu was one of the most-covered Brasilian composers by Brasil '66.
Carlos Lyra was also one of the founders of the Bossa Nova (though he usually takes a back seat to Gilberto and Jobim), whom younger fans will recognize for his work with Santana.
Joyce is a beautiful singer/songwriter with one of the clearest voices (reminiscent of Gal Costa's at times) I've ever heard. She is kind of like a Brasilian Joni Mitchell.
Wanda Sa was Sergio Mendes' original vocalist with Brasil '65. At that time she was married to Edu Lobo (Bena is her son, as well). I believe MBarnum loves Wanda's "Vagamente" album, but maybe I'm making that up. She still performs regularly in Rio with Roberto Menescal.
Joao Donato is simply one of the greatest pianist/composers ever from Brasil. Fans of Brasil '66 will know Joao's great song "The Frog," written with Caetano Veloso. Joao toured with Sergio's other band Bossa Rio in the late 60s and early 70s.
Ivan Lins is without a doubt the most sophisticated songwriter to come out of Brasil over the past quarter century. His brilliant use of altered dominant seventh structures is amazing to see and hear. His sultry song "The Island" has become a modern classic, though everything he writes is magnificent.
