Helton has 3 Terreno Baldio concerts.

Terreno Baldio was a Brazilian progressive rock group. Formed in the early 1970s, they released an homonymous LP in 1975. It was limited to 3000 copies and the master tape was lost, so a re-release was impossible. The line-up was: João Carlos "Fusa" Kurk, died August 11, 2017 (vocal, flute & percussion), Mozart de Mello (guitar), Ronaldo Lazzarini (keyboards), Ascenção (bass) and Joaquim Correia (drums & percussion).
