In contrast to neighboring Kenya, Tanzania's recording industry remains undeveloped. Groups tape annual sessions at the national radio studio, and make their reputations through frequent live shows. Dance clubs have defined the Dar es Salaam scene since the '30s. Once-private social clubs have evolved into government-run establishments that own P.A. equipment and employ musicians to play up to six nights a week. Formed in 1964 under the auspices of National Union of Tanzania (NUTA), Juwata Jazz--now caleld OTTU Jazz--still draw big crowds, and remain the grandfather of all Tanzania's dance bands. Relaxed grooves, lush horn sections and interlocking guitars mark a rumba influence. But Tanzania's long-standing insistence on local content on the radio has fostered a national sound. Composer and singer Muhiddin Maalim helped form Juwata Jazz in '64. After stints with Mlimani Park Orchestra and Orchestra Safari Sound in the '80s, he now leads Juwata Jazz again. Another Juwata veteran, Joseph Lusungu (trumpet and vocals) joined the band along with Mnenge Ramadhani (sax) in 1966 and established the group's brass-oriented sound. In Tanzania, bands adapt one of the traditional ngoma dances as their mtindo, or trademark style. Juwata's mtindo is the drum dance called msondo. The founders of many top groups, including Mlimani Park, had their apprenticeship here, in what remains Tanzania's most durable band.
