The record side at its true size: Bill Dobslaw and the Riviera label — South Bend's — with the record-producer and studio tests set out as negatives, the searches named

1963–1966 · Riviera Records, South Bend (boundary), and the Granger tests

The local label and its man: William "Bill" Dobslaw of South Bend — musician, producer, manager and businessman — discovered the teenage band the Rivieras in 1963, became their manager, booked and financed their first session (an hour at Columbia Recording Studios in Chicago), and created his own Riviera label to press and distribute the record himself: a thousand copies of "California Sun," released October 1963, reaching number five nationally in early 1964 after a Chicago disc jockey picked it up, with national distribution through USA Records of Chicago. Dobslaw oversaw the production, manufacturing and distribution of the band's records for their whole career — eight singles and two LPs in the first run, 1962–66, including the Riviera LP Campus Party (1965) — sang with the band in its later line-ups and himself took the lead vocal in one personnel shift, and signed exactly one other act to the label: the La Porte group that recorded as both the Kastaways and the Sigma Five (one 45 under each name, the Sigma Five's "Comin' Down" credited to Dobslaw as producer), with a sublabel, Shoreline, beside Riviera. The label went defunct with the band, by 1965/66. Two conflicts in the band's own record print whole: the standard band history forms the Rivieras in fall 1962 in South Bend, by five South Bend Central schoolboys, while the Indiana Music Encyclopedia holds that the original members were mostly from nearby La Porte and that the band is only "commonly believed to be from South Bend" — and a second, unrelated Riviera label, a Modern/Crown budget subsidiary of Culver City, California (1959–63), shares the name and is not Dobslaw's. Neither conflict touches the label man's own seat: every source places Dobslaw, and his label's making, in South Bend.

The tests, set out as negatives with the searches named, as the row requires: (1) Label. Discogs' label records and the label discographies were searched by location for Granger, Indiana, and for the county: the county's label of record is Dobslaw's Riviera, South Bend-seated, above; no label seated in Granger appears. (2) Record producer. The same location sweeps and the credit records searched for a record producer born, raised or seated in the CDP returned none; Dobslaw is the county pattern and he is South Bend's. (3) Studio. Indiana recording-studio directories and location searches for a studio in Granger returned no Granger recording studio of record — the searches return South Bend, Elkhart and Indianapolis houses, and, inside Granger's own commercial record as the banked Arts section carries it, music schools and lessons only. Verdict, for this ground: no local label, no record producer, and no recording studio seated in the CDP in any record reached — printed as tested negatives, with the boundary positive (Dobslaw) carried above at its true size so the negative stands on a shown search, not on an omission.
