Success: Layla, At Fillmore East
The Allman Brothers Band went on to become one of the most influential rock groups of the 1970s, described by Rolling Stone's George Kimball in 1971 as "the best damn rock and roll band this country has produced in the past five years." After months of nonstop rehearsing and gigging, including free shows in Macon's Central City Park and Atlanta's Piedmont Park, the group was ready to settle on the Allman Brothers Band name, and to record. Their debut album, The Allman Brothers Band, was recorded in New York in September 1969 and released a few months later. In the midst of intense touring, work began in Macon and Miami (Atlantic South - Criteria Studios), and a little bit in New York, on the band's second album, Idlewild South. Produced mostly by Tom Dowd, Idlewild South was released in August 1970 and broke new ground for them by quickly hitting the Billboard charts.
A group date in Miami, also that August, gave Allman the chance to participate in Eric Clapton's Layla and Other Assorted Love Songs. Clapton had long wanted to meet Allman; when he heard that the Allman Brothers were due to play in Miami, where he had just started work on Layla with producer Tom Dowd, he insisted on going to see their concert, where he met Allman. At one point, Allman approached Clapton, fully admiring his ability to play guitar as much as Clapton admired his, and cautiously asked Clapton if he could come by the studio to watch. Clapton was in no way reluctant to say yes, as he knew that his masterful playing combined with Allman's would be greater than the sum of its parts. After the show the two bands—the Allman Brothers Band and Derek and the Dominos—returned to Criteria, where Allman and Clapton quickly formed a deep rapport during an all-night jam session. Allman wound up participating on most of the album's tracks, contributing some of his best-known work. Allman never left the Allman Brothers Band, though, despite being offered a permanent position with Clapton. Allman never toured with Derek and the Dominos, but he did make three appearances with them on December 1, 1970 at the Curtis Hixon Hall in Tampa (Soulmates LP) and the following day at Onondaga County War Memorial, and one appearance (or possibly just Delaney Bramlett or both Duane and Delaney) November 20, 1970 at the Santa Monica Civic Auditorium, California.
In an interview, Duane told listeners how to tell who played what: Eric played the Fender parts and Duane played the Gibson parts. He continued by nonchalantly noting that the Fender had a sparklier sound, while the Gibson produced more of a "full-tilt screech". Clapton wrote later in his autobiography that he and Allman were inseparable during the sessions in Florida; he talked about Allman as the "musical brother I'd never had but wished I did."
The Allman Brothers went on to record At Fillmore East in March 1971. Meanwhile, Allman continued contributing session work to other artists' albums whenever he could. According to Skydog: the Duane Allman Story, Allman was in the habit of spontaneously dropping in at recording sessions and contributing to whatever was being taped that day. He received cash payments but no recording credits, making it virtually impossible to compile a complete discography of his works.
Allman was well known for his melodic, extended and attention-holding guitar solos. During this period two of his stated influences were Miles Davis and John Coltrane, having listened extensively to Kind of Blue for two years.
As Allman's distinctive electric bottleneck steel sound began to mature it evolved in time into the musical voice of what would come to be known as Southern Rock, being picked up and redefined in their own styles by slide guitarists that included bandmate Dickey Betts (after Duane's passing), Rory Gallagher, Derek Trucks and Gary Rossington of Lynyrd Skynyrd.
