The ngoma buntibe group at Siachilaba takes its name from the composer (mwimbi), called Simonga, who fled with his relatives from fighting chiefs in Zambia to Siachilaba sometime towards the beginning of this century. He was the grandfather of Sialwindi Munkuli, the present leader of Simonga and the keeper of the horns in central Siachilaba today.

In 1994, Simonga presented a performance of Valley Tonga buntibe music as part of a Festival Trail, the last segment of the Houses of Stone Festival organised by KUNZWANA Trust. In 1995, a similar event took place as part of a cultural safari organised by members of the Austria-Zimbabwe Friendship Association in Linz, Austria in conjunction with KUNZWANA.
