Dancers, percussionists and instrumentalists in full costume celebrating the sounds of Brazil make two appearances today. The performances feature Eduardo Mendonça, the founder of the group and a well-known Brazilian recording artist.  Show Brazil combines the music brought to Brazil from the African slaves in the 16th century, Afro-Brazilian war dances, martial arts from the 17th century, reggae and more during a one-hour performance.  Modern and native instruments, including the berimbau â€" a tall, bowed instrument with a gourd â€" are combined with drums and percussion to create the kind of experience that demands clapping and audience participation.  It’s the perfect sunny day event. Aug. 10, noon-1 p.m., free, Washington State History Museum, 1911 Pacific Ave., Tacoma.  7:30-8:30 p.m., free, Pioneer Park, 324 Meridian S., Puyallup. â€" Michael Swan
