How did Sonic Youth get their name?

Shortly after guitarist Thurston Moore moved to New York City in early 1977, he formed a group, Room Tone, with his roommates, who later changed their name to the Coachmen. After the breakup of the Coachmen, Moore began jamming with Stanton Miranda, whose band, CKM, featured Kim Gordon. Moore and Gordon formed a band, appearing under names like Male Bonding and Red Milk and the Arcadians, before settling on Sonic Youth just before June 1981. The name came from combining the nickname of MC5's Fred "Sonic" Smith with "Youth" from reggae artist Big Youth. Gordon later recalled that "as soon as Thurston came up with the name Sonic Youth, a certain sound that was more of what we wanted to do came about."
