Two Man Sound (2 Man Sound)

Two Man Sound was a Belgian pop trio of the 1970s. Their style combined the disco music typical of the era with samba and bossa nova. Their signature hits were "Charlie Brown" and a Latin track called "Disco Samba". Charlie Brown was a success in Belgium and Italy but never broke the United Kingdom. The medley "Disco Samba" became a huge European hit in the early 1980s, with repeated hit-listings in euro-charts from 1983 through 1986. The samba song "Que Tal America" became an 'underground disco anthem' in North America.
