Question: What musician from Assam popularized the double-headed drum widely used, with regional variations, throughout the Indian subcontinent?
Context: Dhol (Hindi: ढोल , Punjabi: ਢੋਲ , Urdu: ‎ , , Gujarati: ઢોલ , Marathi: ढोल , Bengali: ঢোল ) can refer to any one of a number of similar types of double-headed drum widely used, with regional variations, throughout the Indian subcontinent.  Its range of distribution in India, Bangladesh and Pakistan primarily includes northern areas such as the Punjab, Haryana, Delhi, Kashmir, Sindh, Assam Valley, Gujarat, Maharashtra, Konkan, Goa, Karnataka, Rajasthan and Uttar Pradesh.  The range stretches westward as far as eastern Afghanistan.  The Punjabi dhol is perhaps best known abroad due to its prominent place in the rhythm of popular Punjabi bhangra music. A kurta (Hindi: कुर्ता , Bengali: কুর্তা , Punjabi: ਕੁੜਤਾ , Urdu: ‎ ] ) is an upper garment for men and women, originating in the Indian subcontinent, with regional variations of form. Assamese cuisine () is the cuisine of Assam.  It is a style of cooking that is a confluence of cooking habits of the hills that favor fermentation and drying as forms of food preservation, and those from the plains that provide fresh vegetables and abundance of fish from its many rivers and ponds; both of which are centered on the main ingredient—rice.  The confluence of varied cultural influences in the Assam Valley has led to the staggering variety and flavours in the Assamese food.  It is characterised by the use of an extremely wide variety of plant as well as animal products, owing to their abundant availability in the region.  It is a mixture of different indigenous styles with considerable regional variations and some external influences.  The cuisine is characterized by very little use of spices, little cooking over fire and strong flavors due mainly to the use of endemic exotic fruits and vegetables that are either fresh, dried or fermented.  Fish is widely used, and birds like duck, squab etc. are very popular, which are often paired with a main vegetable or ingredient.  Preparations are rarely elaborate mash;the practice of Bhuna, the gentle frying of spices before the addition of the main ingredients so common in Indian cooking, is absent in the cuisine of Assam.  The preferred oil for cooking is the pungent mustard oil. The kakko (羯鼓 or 鞨鼓 ) is a Japanese double-headed drum.  One way in which the "kakko" differs from the regular taiko drum is in the way in which it is made taut.  Like the Shime-Daiko and "tsuzumi", the skin of the heads are first stretched over metal hoops before they are placed on the body, tying them to each other and tightening them making them taut.  "Kakko" drums are usually laid on their sides on stands so that it can be played with sticks called "bachi" on both heads.  Kakko drums have been used in taiko ensembles, but they are also used in older Japanese court music called gagaku. Pellet drums, or rattle drums, are a class of membranophone, or drum, characterized by their construction and manner of playing.  They have two heads (either a single double-headed drum or two hemispherical single-headed drums joined together with the heads facing outward), and two pellets, each connected by a cord to the drum.  The "damaru", which is used in Tibet, Mongolia, and India, is an hourglass drum that is grasped by its waist with the hand twisting back and forth, causing the pellets to strike the heads in a rhythmic fashion.  In China, Korea, and Japan, pellet drums are affixed to or pierced by a vertical rod or pole, and, depending on the instrument's size, the rod or pole is rotated back and forth along its axis either with one or both hands or between the palms, causing the pellets to strike the heads in a similar manner. A Batá drum is a double-headed drum shaped like an hourglass with one end larger than the other.  The percussion instrument is used primarily for the use of religious or semi-religious purposes for the native culture from the land of Yoruba, located in Nigeria, as well as by worshippers of Santería in Cuba, Puerto Rico, and in the United States.  The Batá drum's popular functions are entertainment and to convey messages.  Its early function was as a drum of different gods, drum of royalty, drum of ancestors and drum of politicians.  Batá drum impacted on all spheres of life. Bangladeshi cuisine refers to the food and culinary traditions prevalent in Bangladesh.  Dating far in the past, the cuisine emphasizes fish, vegetables and lentils served with rice.  Because of differences in history and Bangladeshi geography, the cuisine is rich in regional variations.  While having unique traits, Bangladeshi cuisine is closely related to that of surrounding Bengali and North-East Indian, with rice and fish traditional favorites.  Bangladesh also developed the only multi-course tradition from the Indian subcontinent.  It is known as "Bengali Kita" styled cuisine.  The Bangladeshi food is served by course rather than all at one time. Srimanta Sankardev ([ˈʃrɪˌmʌntə ˈʃænkə(r)ˌdeɪv]; 1449–1568) () was a 15th–16th century Assamese polymath: a saint-scholar, poet, playwright, social-religious reformer and a figure of importance in the cultural and religious history of Assam, India.  He is widely credited with building on past cultural relics and devising new forms of music (Borgeet), theatrical performance (Ankia Naat, Bhaona), dance (Sattriya), literary language (Brajavali).  Besides, he has left an extensive literary oeuvre of trans-created scriptures (Bhagavat of Sankardev), poetry and theological works written in Sanskrit, Assamese and Brajavali.  The Bhagavatic religious movement he started, Ekasarana Dharma and also called Neo-Vaishnavite movement, influenced two medieval kingdoms---Koch and the Ahom kingdoms—and the assembly of devotees he initiated evolved into Sattras over time, which continue to be important socio-religious institutions in Assam and to a lesser extend in North Bengal.  Sankardev inspired the Bhakti movement in Assam just as Guru Nanak, Ramananda, Kabir, Basava and Chaitanya Mahaprabhu inspired it elsewhere in the Indian subcontinent.  His influence spread even to some kingdoms as the Matak Kingdom founded by Bharat Singha, and consolidated by Sarbanda Singha in the latter 18th century endorsed his teachings. The tamak' is a stick-struck double-headed drum of the Santal people of India.  The body of the drum is made from metal and shaped like a large bowl.  The head of the drum is usually cowhide and 14-18 inches in diameter.  The player strikes the drum with a pair of drum sticks.  The Santal believe that the tamak' has special religious powers and it is often used for religious ceremonies and Santal festivals.  The rhythm of the Tamak' often sets the basic metric/rhythmic pattern for Santal dances and is an essential instrument for traditional Santal music.
