Spark enjoyed immediate success with the Robins' RB smash Riot in Cell Block #9. The group's follow-up, Smokey Joe's Café, proved an even bigger hit, in fact too big for the small label to handle. So in 1955 Spark sold its catalog to Atlantic Records, which in turn named Sill its national sales manager while giving Lieber and Stoller an independent production deal; while the deal prompted the breakup of the Robins, members Carl Gardner and Bobby Nunn continued on as the Coasters, with Sill serving as their manager. The Coasters would emerge as one of the most popular RB acts of the late '60s, generating a series of wry Lieber and Stoller-penned hits including Down in Mexico, Yakety Yak, and Charlie Brown; Sill also enjoyed chart success teaming with producer-songwriter Lee Hazlewood on 1958's Rebel Rouser, the most notable of the 15 Top 40 instrumentals headlined by the renowned guitarist Duane Eddy and issued on the Dick Clark-owned Jamie label. In late 1959 Sill and Hazlewood formed Trey Records, a Hollywood-based imprint distributed by Atlantic. The label's signings included 18-year-old wunderkind Phil Spector, then fresh off the success of his group the Teddy Bears' chart-topping pop classic To Know Him Is to Love Him. Spector produced several Trey sides. None were hits, but Kell Osborne's 1960 release The Bells of St. Mary's bears all the dramatic hallmarks that would later define his trademark Wall of Sound aesthetic.
At the end of 1961, Sill and Hazlewood shut down Trey but quickly formed a new label, Gregmark, as a vehicle for the Paris Sisters, an Andrews Sisters-inspired sibling vocal trio with a series of little-heard Decca singles under its belt. Sill insisted on a top-to-bottom overhaul of their approach, prompting Spector to relegate Albeth and Sherrell Paris to the background while turning the spotlight on youngest sib Priscilla, insisting she dial back her powerful voice to a dusky whisper. While the Paris Sisters' Gregmark debut Be My Boy earned little notice, the follow-up, I Love How You Love Me, cracked the U.S. Top Five, galvanized by Priscilla's intimate lead turn and Spector's atypically restrained production. Spector then began work on a Paris Sisters LP, but as production costs began to skyrocket, Sill attempted to exert control of the project. Their skirmish ended disastrously when, according to Sill, one of his assistants accidentally discarded the master tapes, although rumors persist of a far more nefarious outcome. At the same time Sill's partnership with the tempestuous Hazlewood collapsed, and despite their differences, in late 1961 Sill and Spector inaugurated their own label, Philles, immediately reaching the Top 20 with the company's debut release, the Crystals' There's No Other (Like My Baby). Its 1962 follow-up, Uptown, was Spector's first true tour de force, capturing the Wall of Sound in full gallop.
By mid-1962 Philles was the most successful independent label in the U.S., scoring a series of Spector-produced classics including the Crystals' He's a Rebel and Then He Kissed Me, Bob B. Soxx the Blue Jeans' Zip-a-Dee-Doo-Dah and the Ronettes' Be My Baby. But as Spector's fame and renown grew, so did his notorious ego, and as he exerted more and more of his mercurial will over Philles' business dealings, his relationship with Sill disintegrated. Spector eventually forced his mentor out of the company altogether, buying out Sill for a paltry 60,000 dollars (reportedly never even paid) and decisively terminating their partnership with the never-released Crystals recording (Let's Dance) The Screw. After over a year in seclusion, in 1964 Sill resurfaced as a consultant to Screen Gems-Columbia Music president Don Kirshner. Although the position was temporary, he ended up staying with the company for over two decades, eventually taking over Kirshner's position. In 1985 Sill was named president and CEO of Jobete Music, the publishing arm of Berry Gordy, Jr.'s Motown empire. He remained with Jobete until his death in Los Angeles on October 31, 1994. ~ Jason Ankeny, Rovi
