His murder comes one week before a general election, in which South
Africa's high crime rate is an important issue.
About 20,000 people are murdered in South Africa each year.
Wallet stolen
Gito Baloi, 39, was driving home from a gig in Pretoria when he was
attacked.
Eyewitnesses say he was shot three times through the window of his car
by two men as he dropped off a friend in central Johannesburg.
Mr Baloi managed to stagger away from his car, before he collapsed and
died. The murderers took his wallet.
But while the motive appeared to be robbery, his musical equipment was
left at the scene.
The bass guitarist's musical career had a humble beginning, as he
performed his first live gigs with a borrowed instrument in his native
Mozambique.
His innovative sound reached South Africa during a 1986 tour.
He became co-founder of the band Tananas, famous in South Africa for its
eclectic contemporary jazz styles.
He also released several solo albums and formed his own band in the late
1990s.
Soweto killing
The BBC's Barnaby Phillips in Johannesburg says authorities in the city
have put considerable efforts into reducing crime in the notorious city
centre.
But this brutal killing of one of Southern Africa's most respected
musicians shows that there is still much to be done, he says.
This is the second killing of a high profile musician in Johannesburg
this year - in February the lead singer of the band Mafikizolo, popular
with young black people, was shot in Soweto in a road-rage incident.
South Africans go to the polls next week; and violent crime is once
again an important issue.
The governing ANC says that crime has stabilised and the largest
opposition party, the Democratic Alliance, has promised to put tens of
thousands of extra policemen on the streets.
