By 1985, with Yunupingu on vocals and guitar, he formed a Yolngu band including Witiyana Marika on
manikay (traditional vocals),
bilma (ironwood
clapsticks) and dance, Milkayngu Mununggurr on
yidaki (
didgeridoo), and
Gurrumul Yunupingu – his nephew – on keyboards, guitar and percussion. The following year the Yolngu group combined with a
balanda (non-Indigenous) group, Swamp Jockeys, which had Andrew Belletty on drums, Stuart Kellaway on bass guitar and Cal Williams on lead guitar. The band achieved national recognition for their single, "
Treaty", the remixed version was released in June 1991, which reached No. 11 on the
ARIA Singles Chart and stayed in the top 50 for 20 weeks. Mandawuy and Galarrwuy had wanted a song to highlight the lack of progress on a treaty between Aboriginal peoples and the federal government. The song contains words in Gumatj, Yunupingu's variety of
Yolngu matha. It was written by Australian musician,
Paul Kelly, with Yothu Yindi members Yunupingu, Kellaway, Williams, Gurrumul, Mununggurr and Marika. The associated album,
Tribal Voice appeared in October 1991, which peaked at No. 4 on the ARIA Albums Chart. Nevertheless both "Treaty" in 1992 and "Djäpana (Sunset Dreaming)" in 1993 charted on the
Billboard Hot Dance Club Play singles charts, with "Treaty" peaking at No. 6,
Tribal Voice peaked at No. 3 on the
Billboard Top World Music Albums chart in 1992. In 1991 "Treaty", co-written by Yunupingu, won the inaugural Song of the Year Award at the
APRA Music Awards presented by
Australasian Performing Right Association. In May 2001 it was listed in the
APRA Top 30 Australian songs of all time. Yothu Yindi completed four more studio albums,
Freedom (November 1993),
Birrkuta - Wild Honey (November 1996),
One Blood (June 1999) and
