Push Push is a 1971 instrumental album by jazz flautist Herbie Mann, on his Embryo Records label with Atlantic, which features rock guitarist Duane Allman. The record explored a range of popular genres, such as R&B, rock and funk music to create what Allmusic calls a "generally appealing, melodic and danceable" album with an "impressive crew of musicians."^[2][3]

Herbert Jay Solomon (April 16, 1930 – July 1, 2003),^[1] known by his stage name Herbie Mann, was an American jazz flautist and important early practitioner of world music. Early in his career, he also played tenor saxophone and clarinets (including bass clarinet), but Mann was among the first jazz musicians to specialize on the flute and was perhaps jazz music's preeminent flautist during the 1960s. His most popular single was "Hijack," which was a Billboard number-one dance hit for three weeks in 1975.

Mann emphasized the groove approach in his music. Mann felt that from his repertoire, the "epitome of a groove record" was Memphis Underground or Push Push, because the "rhythm section locked all in one perception." ^[2]

Howard Duane Allman (November 20, 1946 – October 29, 1971) was an American guitarist, session musician and the primary leader and co-founder of the The Allman Brothers Band, until his death in a motorcycle accident in 1971 at the age of 24.

The Allman Brothers Band was formed in 1969 and, unusual for the time, based in theSoutheastern United States. In the early 1970s the band was hugely successful. Duane is best remembered for his brief but influential tenure in the band, and in particular for his expressive slide guitar playing and inventive improvisational skills.^[1] In 2003, Rolling Stonemagazine ranked Allman at #2 in their list of the 100 greatest guitarists of all time, second only to Jimi Hendrix and in 2011 he was ranked #9.^[2] His tone (achieved with a Gibson Les Paul and two 50-watt bass Marshall amplifiers) was named one of the greatest guitar tones of all time by Guitar Player.^[3]

A sought-after session musician both before and during his tenure with the band, Duane Allman performed with such established stars as King Curtis, Aretha Franklin, Wilson Pickett, and Herbie Mann. He also contributed heavily to the 1970 album Layla and Other Assorted Love Songs by Derek and the Dominos.

Duane Allman’s skills as a guitarist were complemented by personal qualities such as his intensity, drive and ability to draw the best out of others in making music.^[4] He is still referred to by his nickname "Skydog".^[5]

The video below and song capture a unique time in American music history, when black soul and southern rock'n'roll legends worked together making incredible music, without concern for the racial turmoil raging through the country in the mid to late 60's.

Music had no color, and in Fame Studios, Muscle Shoals, Alabama, it was the music that mattered most of all. The Fame Studio's session players featured guitarist Duane Allman, as well as drummer Ronnie Hawkins and bass player David Hood. They played on many varied artists records, but made their most memorable music with soul musicians like Aretha Franklin and Wilson Pickett. 

Duane's work on Wilson Pickett's album "Hey Jude" got him hired as a full-time session musician at Muscle Shoals and brought him to the attention of a number of other musicians, such as guitar great Eric Clapton, who later said, "I remember hearing Wilson Pickett's 'Hey Jude' and just being astounded by the lead break at the end. ... I had to know who that was immediately — right now."

In a short time, Skydog became equal to the most prominent musicians of his time. His work with Clapton (as part of Derek and The Dominos), Aretha Franklin, Wilson Pickett, John Hammond Jr., Herbie Mann and King Curtis displayed Duane's breadth and scope of ability. Equally vital was the insight of the offstage talents: Tom Dowd, Jerry Wexler and Rick Hall. 

While at Muscle Shoals, Allman was featured on releases by a number of artists, including Clarence Carter, Otis Rush, Percy Sledge, Johnny Jenkins, Boz Scaggs, Eric Quincy Tate, Lulu, Ronnie Hawkins, Doris Duke, Sam Samudio, Cowboy, Arthur Conley and Delaney & Bonnie and Friends. Duane would often just show up at Muscle Shoals to play, getting paid cash for his time but being uncredited on the recordings! He is suspected to have played on countless more Fame Studio releases, but many cannot be confirmed.

The nickname "Skydog" is a blending of Duane's two older nicknames. Wilson Pickett dubbed Duane "Skyman Allman". Pickett called him "Skyman" because of his soaring playing and personality (or because he liked to get high, depending on the story). Duane's friends often called him "Dog" because of his thick sideburns, long hair and shaggy looks. "Skydog" is a combination of the two. Duane Allman is among the most famous players of electric slide guitar, and almost certainly the greatest. Duane played bottleneck slide using a glass Coricidin D cold medicine bottle, and usually tuned his guitar to open E.  [Acknowledgement & Thx to Clayopalstar @ Youtube.com ]
