Despite predictions of failure by many in the Burmese music industry, the album, Beginning, remained in the number one position of the Burmese charts for more than two months.^[1] A Democratic Voice of Burma reporter described his music as blending a "combative, angry style with indigenous poeticism".^[2] The band's repertoire has been said to contain many "thinly veiled attacks on the regime".^[3] The Independent stated that while the band "focused on the mundane, their lyrics inevitably touched on the hardships of life in Burma, drawing them into dangerous territory."^[4]

Following the 2007 uprising against the State Peace and Development Council, Burma's military rulers, Yan Yan Chan's bandmate Phyo Zeya Thaw helped found the pro-democracy youth movement Generation Wave.^[1] Though not an original founder, Yan Yan Chan became involved in the group as well.^[5] Generation Wave used graffiti and pamphlets to spread messages opposing the SPDC.^[1] and distributed bumper stickers reading "Change New Government" to apply to cars carrying "CNG" stickers (originally for "compressed natural gas").^[1] The group also circulated anti-government films, including Rambo,^[6] in which the titular character battles Tatmadaw (Burmese military) soldiers in Karen State.^[7] The film had been banned by the government for portraying the SPDC and its soldiers in a negative light.^[8]

In March 2008, several Generation Wave members were arrested for their anti-government activities, including Phyo Zeya Thaw, who was charged with membership in an illegal organization and possession of foreign currency.^[9] On 18 April, Yan Yan Chan was also arrested in the Upper Burma town of Monywa, reportedly along with his longtime girlfriend Chilli.^[5][10] Reporters Without Borders speculated that Yan Yan Chan was arrested due to "lyrics in some of his songs referring to the lack of press freedom".^[11] After nearly a year's detention, he was released without charges on 7 January 2009.^[5]
