Record Store Day, now in its fourth year, falls on the third Saturday of April (4/17) and brings together "over 700 independently owned record stores in the USA" and "hundreds of similar stores internationally" to form a sort of one-shot record club that excludes "online retailers or corporate behemoths." Festivities include free in-store performances, promotional giveaways, and discounts, in addition to a horde of releases and reissues—many of them limited, and some of them superlimited—available only at participating stores. You might want to get up early: last year a line formed outside Reckless Records on Milwaukee before the doors opened. Some 20 Chicago record stores are participating this year.

Local labels are in on the act too. The in-house label at Permanent Records is releasing, in an edition of 750, a split seven-inch featuring Moon Duo and the Cave side project Bitchin' Bajas. Bloodshot has an exclusive Ha Ha Tonka seven-inch, in an edition of 500. Trouble in Mind is releasing a four-way split single featuring Ty Segall, CoCoComa, White Wires, and Charlie & the Moonhearts. Also, the Brooklyn-based film and music label Factory 25 unveils full-length vinyl albums from two early Chicago punk bands, featuring a collection of demos (1977-'78) from Tutu & the Pirates called Sub-Urban Insult Rock for the Anti-Lectual and the DA full-length Exclamation Point.

Other enticements include vinyl reissues from Mastodon, Devo, Joe Strummer & the Mescaleros, MGMT, Sonic Youth, and the Velvet Underground; live recordings by David Bazan at Electrical Audio and Hot Water Music at Metro; early releases of a ten-inch vinyl version of Magnetic Fields' reissued 69 Love Songs set and new albums from the Apples in Stereo and Roky Erickson with Okkervil River; a clear vinyl release of Neko Case's Middle Cyclone; a seven-inch of Fucked Up's Daytrotter session; a colored-vinyl reissue of the double LP Ramones Mania; and a number of reissues with original artwork from Vanguard (Buddy Guy, Doc Watson, Joan Baez, John Fahey) in celebration of the label's 60th anniversary.

Below are participating stores in the city and near suburbs, along with the events, sales, giveaways, and performances planned. Call stores or visit their Web sites for more info; for a more complete list of special releases and happenings see recordstoreday.com. —Kevin Warwick
