Question: When did the explorer reach the headquarters location of the group Con-Test's record label is part of?

<P0-S0> MCA Records was an American record label owned by MCA Inc., which later gave way to the larger MCA Music Entertainment Group (now Universal Music Group), which the label was part of until its dissolution in 2003. <P0-S1> The label's country division MCA Nashville is a still active imprint of Universal Music Group Nashville. <SEP> <P1-S0> arc was acquired in 1938 by the columbia broadcasting system (cbs, which, in turn, had been formed by the columbia phonograph company, but then sold off). <P1-S1> arc was renamed columbia recording corporation. <P1-S2> the columbia phonograph company had international subsidiaries and affiliates such as the columbia graphophone company in the united kingdom, but they were sold off prior to cbs acquiring american columbia. <P1-S3> rca victor records executive ted wallerstein convinced cbs head william s. paley to buy arc and paley made wallerstein head of the newly acquired record company. <P1-S4> the renamed company made columbia its flagship label with okeh its subsidiary label while deemphasizing arc's other labels. <P1-S5> this allowed arc's leased labels brunswick records and vocalion records to revert to former owner warner bros. which sold the labels to decca records. <P1-S6> columbia kept the brunswick catalogue recorded from december 1931 onward which was reissued on the columbia label as well as the vocalion label material from the same time period which was reissued on the okeh label. <P1-S7> wallerstein, who was promoted at the end of 1947 from president to chairman of the record company, restored columbia's status as a leading record company and spearheaded the successful introduction of the long playing (lp) record before he retired as columbia's chairman in 1951. james conkling then became head of columbia records. <P1-S8> also in 1951, columbia severed its ties with the emi-owned record label of the same name and began a uk distribution deal with philips records, whereas okeh records continued to be distributed by emi on the columbia label. <SEP> <P2-S0> The Right Stuff Records is a reissue record label that was part of EMI, which is now owned by Universal Music Group and is based out of Santa Monica, California. <SEP> <P3-S0> rca/jive label group ceo barry weiss left the company in march 2011 to become the new ceo of island def jam and universal republic, which were both part of universal music group. <P3-S1> weiss had been the rca/jive label group ceo since 2008 and was head of jive records since 1991. <SEP> <P4-S0> MCA Records picked up the reissue rights for "Con-Test", as well as Nash's "American Band-ages" in 1986, but the abrupt change in record labels led to a near-absence of promotion for both records. <SEP> <P5-S0> Santa Monica was long inhabited by the Tongva people. <P5-S1> Santa Monica was called Kecheek in the Tongva language. <P5-S2> There are two different versions of the naming of the city. <P5-S3> The first non-indigenous group to set foot in the area was the party of explorer Gaspar de Portolà, who camped near the present day intersection of Barrington and Ohio Avenues on August 3, 1769. <P5-S4> One says that it was named in honor of the feast day of Saint Monica (mother of Saint Augustine), but her feast day is actually May 4. <P5-S5> Another version says that it was named by Juan Crespí on account of a pair of springs, the Kuruvungna Springs (Serra Springs), that were reminiscent of the tears that Saint Monica shed over her son's early impiety.
