Hier schon mal ein Appetitanreger aus dem Netz:
The Heilichers co-founded Soma Records in 1957 -- the name was "Amos" spelled backwards. While the label initially focused on local polka music, country, and jazz artists, in 1959 Heilicher signed Fargo, ND-born rocker Bobby Vee, who debuted with the Buddy Holly-inspired "Suzie Baby." When the single emerged as a regional smash, Liberty Records licensed the master for national distribution and acquired the singer's contract by year's end. With the money earned from the Liberty deal, Soma licensed from Wisconsin label Cuca rockabilly duo the Fendermen's rendition of the Jimmie Rodgers classic "Mule Skinner Blues." The record proved an unexpected blockbuster, selling over a million copies and reaching number three on the Billboard pop chart. From there the Heilichers rattled off a series of hits that established Soma among the premier American independent labels of the '60s -- national hits like the Trashmen's "Surfin' Bird," the Castaways' "Liar Liar," and the Gestures' "Run, Run, Run" remain quintessential examples of the surf and garage rock ethos that dominated radio in the first half of the decade. With their recording and distribution units now firing on all cylinders, the Heilichers acquired Musicland in 1964 , at that time a 15-store retail chain founded eight years earlier by Minneapolis entrepreneurs Terry Evenson and Grover Sayre. In 1968, with the business expanded to 48 locations across the Midwest, the siblings merged Musicland with Pickwick International, the American record label and distributor notorious for its soundalike releases and bargain-bin reissues. The merger also heralded the demise of Soma, which was consolidated under the Pickwick Records aegis.
Eine andere Quelle bezüglich den Kay Bank Studios:
Apart from Starday and Rite, no other custom pressing company fascinates me as much as the famed Kay Bank Studios custom pressing division. Even the musically poor records issued by Kay Bank seem to have a certain charm. But, like most things regarding custom pressed records, the information I have about the facility is scant to say the least.
According to Wikipedia (which isn’t the safest source to take info from), the Kay Bank studios were originally located at 2541 Nicollett Ave, Minneapolis, MN and was run by Amos & Daniel Heilicher (Amos owned the Soma Label). Yet Minniwiki (the Minnesota Music Encyclopedia) it was owned by John Michaelson. To make it worse, my notes states that Kay Bank Custom Pressing Division was run by Vern Banks! An Article about Billy Peterson in the Encyclopedia of Jazz Musicians states the Studio owner was Bruce Swedien!
