I love the first song, Berbs.
It's played by Eddie Hazel.
According to legend, George Clinton, under the influence of LSD, told Eddie Hazel during the recording session to imagine he had been told his mother was dead but the rumor wasn't true.[1] The result was the 10-minute guitar solo for which Hazel is most fondly remembered by many music critics and fans. Though several other musicians began the track playing, Clinton soon realized the power of Hazel's solo and faded them out so that the focus would be on Hazel's guitar. Critics have described the solo as "lengthy, mind-melting" and the ending as "an emotional apocalypse of sound."[5]
The entire track was recorded in one take. The solo is mostly played in a pentatonic minor scale in the key of E over another guitar track of a simple arpeggio. Hazel's solo was played through a fuzzbox and a Crybaby Wah wah pedal; some sections of the song utilize a delay effect. This style would be revisited later in Standing on the Verge of Getting It On on the track "Good Thoughts, Bad Thoughts". The original version with full band accompaniment was released in 1997 on the album "Funkadelic Finest".
