Tribal dance-pop party of two, Okapi Sun, releases Techno Prisoners.

This week’s new releases include First Flask from barroom rockers Ass Pocket Whiskey Fellas, as well as a four-song EP from boogie masters Shakedown Daddies called Shake’n. Reunited bluegrass stars Nickel Creek will drop A Dotted Line on April 1 via Nonesuch Records, with a support tour hitting downtown’s Balboa Theatre on May 20.

Electronic duo Bruin premiers their D’nealian album on April 1 at the Soda Bar in City Heights. “It’s gonna be a combination digital and USB release,” says Dominic Fawcett, “and we’ll also be selling a limited number of cassette tapes. However, since cassette tapes are outdated, pretentious, and generally shit, we’re using them as jump drives. The cassette drives will have the album, the music video, and a bunch of extras.”

No Kings will debut a new CD EP on April 4 at Winstons in O.B. Americana-alt duo Sometimes Julie has a new CD dropping April 10 at 98 Bottles in Little Italy.

Progressive reggae-fusion rockers Project: Out of Bounds will release their first CD in nearly five years on April 11 at Winstons. “The EP features Ivan Garzon of the Devastators, who have been a highly influential band for us, and he’ll make a cameo at the show,” says Kris Asgharzadeh. Sledding with Tigers are going folk-punk for A Necessary Bummer, due April 15 from Antique Records.

Prog-punkers Dead as Dillinger are dropping their Mad Man EP on April 25 at the Ken Club. “Our last recording was back in 2006 at Capricorn Studios,” says singer/bassist Roman Terenzini. “We have a ton of original material, but, like most, we are a band on a budget.” The bill also includes Bella Novela and Like Shatter Diamonds.

Having been dropped by the Epic label, Augustana signed a multi-album deal with Washington Square (the Hold Steady, Deaf Havana), which will release their fourth studio album Life Imitating Life on April 22. A spring tour with Twin Forks and Chris Carrabba hits Soma on April 27.

Tribal pop dance-party enthusiasts Okapi Sun are offering up their 11-track Techno Prisoners album on April 29, courtesy of Phaedra Records. Recorded with Ethan Allen of Gram Rabbit and produced by Grammy-winner Neal H. Pogue (Nicki Minaj, Franz Ferdinand), its first single, “Johnny Kiss,” is available online as a free download.
