This week on Conversations from the World Cafe, the band Train joins host David Dye. While Train may have caught some attention with their 1998 debut, it was 2001's Drops of Jupiter that went multiplatinum. Since that success the band has put out two more discs and recently took a short break, during which singer Pat Monahan launched a solo career. Now they are back with Save Me, San Francisco, a record that recalls their start in that West Coast city. They talk about their early days and what renewed their creativity.

And -- Tropicalia legends Os Mutantes. The Brazilian band made a substantial contribution to the homegrown genre which brought together Brazilian and African rhythms with psychedelic rock and roll. Thirty years since their last release, the group has re-formed -- guitarist and founder Sergio Baptista reflects on their popularity at home, and their new work together.
