For its 45th show, the 45 Sessions will host Natasha Diggs and Danny Holloway at Legionnaire Saloon (2272 Telegraph Ave., Oakland). Diggs and Holloway are famous in New York City and Los Angeles, respectively, for spinning vinyl on 45s: Self-described treasure hunters and vinyl collectors, they’re sure to bring their extensive catalogs and devotion to cratedigging to the festivities. Diggs, who opens a party for Q-Tip every week in New York, is partial to funk, soul, disco, and house. Holloway is an avid reggae fan — he spent a year living in Jamaica and worked on three Bob Marley albums. With their presence, the 45 Sessions — during which local DJs Platurn, E Da Boss, Enki, Delgado, and Mr. E typically spin soul and funk — should be even more eclectic than usual.
