Located between Surakarta (Solo City and Demak), Grobogan has a strong influence of both the more direct Islam Culture from the Sultane of Demak and more subtle culture of Kingdom of Surakarta (Kasunanan Surakarta). This has been reflected in its traditional arts and performances, such as Shadow Puppet (Wayang Kulit), Javanese Theatre (Kethoprak). Although they almost disappear from the local society, those two forms of performances can still be easily found in different parts of Central Java. Other forms of cultural performances are almost wiped out from the live of Groboganese, such as Angguk, Kentrung, Ledhek/Tayup, Barongan and Reyog. Angguk was performed mainly by a group of young girls aged between 13 and 17 years, doing a marching dance inspired by the different forms of old Dutch army and royal army from Demak and Surakarta. Kentrung is a story telling in a form of songs performed by a man with the accompaniment of a traditional percussion (kendang). The stories were mainly based on the local history or the history of Prophet Mohammed. It is possible that Kentrung was used to spread out the teaching of Islam. Ledhek/Tayub is a group of Javanese musicians and singer-dancers which was very popular due to their sensual gestures. Apart from the sensual gestures of the dancers, Tayup was/is also famous since they involve/invite the spectators to dance along with them. This kind of participative performance is rare in the Javanese context. Barongan is a Javanese version of Barongsay, the dance of Dragon, where the influence of Chinese culture can be seen from the form of the dragon, the use of the dominance red color. The difference with the Barongsay, Barongan normally presided Reyog, a trance dance. Reyog in Purwodadi was different with the more extravagance Reyog of Ponorogo. In the middle of the trance, some of the dancers could involve the eating of broken glasses and raw skins of rice (brambut).
