In 1982, Titas (at that time "Titas do Ie-Ie") made their first live presentation. They recorded several tapes and sent them to recording labels until they signed up with Warner Music label. In 1984, Titas released their first album, Titas, and Nando played the bass guitar in some tracks although initially he was supposed to be a backing vocalist only. In the late 1980s, Titas caught a plane to London, for their first international show. On June 19, 1989, his mother Cecilia died of cancer.  In the early 1990s, he started producing his first albums, with artists like Marisa Monte and Cassia Eller. In 1995, he recorded his first solo album, 12 de Janeiro. In 2000, Titas changed to Abril Music, and after recording As Dez Mais in Seattle, Nando released his second solo album, Para Quando o Arco-Iris Encontrar o Pote de Ouro, with some special participations like Cassia Eller, Rogerio Fausino (from Jota Quest) and Peter Buck (from R.E.M.).  On June 13, 2001, Titas' guitarist Marcelo Fromer died after being rammed by a motorcycle (see Marcelo Fromer's Death). On December 29, he lost another friend: Cassia Eller. In 2002, he released Infernal, his third solo work. He then decided to leave Titas on September 9, 2002, partially due to the impact of both friends' deaths caused in his life, but mainly due to a "thought incompatibility". In a later interview, he said that he left the group also due to his will to give more attention to his solo works. He even proposed that the band stopped for one year after the album release. He also said that his isolation as a composer grew more evident in more recent albums, with more and more songs being composed just by him. Nowadays, Reis and Titas are in good terms.  Still in 2002, he produced and guest performed in Eller's Acustico MTV album, which was later nominated for 2002 Latin Grammy Award for Best Brazilian Rock Album; and won it.
