roster featured Stewart Copeland performing with a diverse group of international musicians including: Percussion de Guinnea, a leading drum group from Africa; Vinx, who recently toured with Sting; and Ray Lema, an original performer on the Rhythmatist album and video. Starting in 1998, Uakti recorded fewer original compositions and concentrated on adaptations of classical music and of Brazilian popular songs. The soundtrack of the 1998 film Kenoma, by Eliana Caffé, used mostly compositions by Heitor Villa-Lobos. In 2000 they recorded an album of popular songs with the choral group Tabinha, from Minas Gerais. In 2002, they released the CD Clássicos, containing solely classical arrangements, and in 2005 they explored popular Brazilian themes in the CD Oiapok XUI, which, in addition to various popular Brazilian dance themes, contained four variations of Tom Jobim's Águas de Março. Uakti frequently took part in projects with other artists. Besides the already-mentioned Milton Nascimento, Paul Simon and Manhattan Transfer, they worked with Ney Matogrosso, Maria Bethânia, and Zélia Duncan. They also performed in the show Dança das Marés, directed by Ivaldo Bertazzo, Ihú - Todos os Sons, which presented indigenous themes collected and adapted by Marlui Miranda. Their recording "Trilobita" was used in the closing credits of the Rush in Rio DVD. Instruments The original instruments constructed by Marco Antônio Guimarães are responsible for the group's sound. The list below describes some of these instruments. Pans All of these follow the same basic principle: PVC tubes of various lengths, assembled so that their ends are aligned. The tubes are struck with a rubber mallet or with the hands. Since each length of tubing produces a different note, these instruments are tuned and can play melodies or chords. Currently, they are used in two sizes: the large pan of bent tubing that allows a larger length and is used as a bass, and the shorter inclined pan, used for principal melodies. Marimbas These are idiophones consisting of keys struck with mallets with heads made of rubber or felt. They are played like a xylophone or vibraphone. The difference between Uakti's marimbas and these instruments is that the keys are located above two independent sound boxes that can be inverted or moved. This allows the playing of chords or sequences that would be quite difficult using the traditional design. Uakti uses two kinds of marimbas: Marimba d'Angelim – made of wood used in everyday construction, or Angelim
