Prelude feat. Ziyan Tung

成立於1998年的地底樂團，緩慢地踏入20年。 率先發表由馬來西亞音樂人Ziyan Tung創作的《Prelude》，用上木結他清新簡約的曲風，為地底樂團20周年一系列的主題音樂創作掀起了序幕。 Founded in 1998, the Underground slowly entered 20 years. The first to publish "Prelude" by Malaysian musician Ziyan Tung, using the fresh and simple style of Acoustic Guitar, set off a series of theme music creation for the 20th anniversary of the Underground.
