Nevertheless, four of their ten songs that reached the Hot 100 had no mention of the title in the lyrics: "Immigrant Song", "Black Dog", "Over the Hills and Far Away", "D'yer Mak'er". Their debut album, "Led Zeppelin" (1969), released by Atlantic Records, charted at number six on the UK Albums Chart and at number ten on the United States "Billboard" 200.

Document 5: Electric guitar: An electric guitar is a fretted stringed instrument with a neck and body that uses a pickup to convert the vibration of its strings into electrical signals. The vibration occurs when a guitarist strums, plucks, fingerpicks, or taps the strings. It is sensed by a pickup, most commonly by a magnetic pickup that uses the principle of direct electromagnetic induction. The signal generated by an electric guitar is too weak to drive a loudspeaker, so it is plugged into a guitar amplifier before being sent to a loudspeaker, which makes a sound loud enough to hear. The output of an electric guitar is an electric signal, and the signal can easily be altered by electronic circuits to add "color" to the sound or change the sound. Often the signal is modified using effects such as reverb and distortion and "overdrive", with the growling sound of the latter being a key element of the sound of the electric guitar as it is used in blues and rock music.

Document 12: Tal Farlow: Talmage Holt Farlow (June 7, 1921 – July 25, 1998) was an American jazz guitarist. He was nicknamed "Octopus" because of how his large, quick hands spread over the fretboard. Where guitarists of his day combined rhythmic chords with linear melodies, Farlow placed single notes together in clusters, varying between harmonically enriched tones. As music critic Stuart Nicholson put it, "In terms of guitar prowess it was the equivalent of Roger Bannister breaking the four minute mile."
Document 13: Guitar battle: A guitar battle (or "guitar duel") is where two or more guitar players take turns soloing, either with or without a rhythm section. The purpose of the guitar battle is to determine who among each of the guitar players present is the most proficient on the instrument. Often, it begins with the guitarists trading licks and phrases, while gradually increasing the complexity of the technique used. A guitar battle can be said to be over when one guitarist outplays (either through skill, endurance or the other guitarist(s) acknowledging that they cannot win) all the other guitar players present. This is also known among guitarists as a "head-cutting" duel or simply as "cutting heads".
Document 14: Dive bomb: Dive bomb is a guitar technique in which the vibrato bar is used to rapidly lower the pitch of a note, creating a sound considered to be similar to a bomb dropping. One of the most recognized pioneers of this technique is Jimi Hendrix. Other notable musicians who are widely known for using this technique are Herman Li, Eddie Van Halen, Brian May, Joe Satriani and Tom Scholz of Boston. Some guitarists, such as K.K. Downing, Glenn Tipton, Jeff Hanneman and Dimebag Darrell have been known to use a variation of this technique in which a harmonic, most commonly a pinch harmonic, is used instead of a normal fretted or open note creating a sound arguably closer to that of a bomb due to the squealing sound created by the harmonic.
Document 15: Guitar showmanship: Guitar showmanship involves gimmicks, jumps, or other stunts with a guitar. Some examples of guitar showmanship would become trademarks of musicians such as Chuck Berry, Jimi Hendrix, Pete Townshend, Jimmy Page, Ritchie Blackmore, Eddie Van Halen, Stevie Ray Vaughan, Ace Frehley, and Angus Young.
