4749 Ledzeppelin           Discovered 1989 Nov. 22 by N. Kawasato at Uenohara.
Led Zeppelin were a band from the UK whose 9 albums (1969-1982) made them one of the most influential acts in rock history. They were known for their electric guitar driven sound and lengthy live jams. Considered one of the progenitors of Heavy Metal, their style drew mainly from blues and folk music.
