Record Store Day returns for its ninth iteration on Saturday, and though the Reader joked that this ersatz holiday had jumped the shark four years ago, it continues to thrive. I'm pretty ambivalent about RSD by now—it sometimes feels like the only thing separating people who queue up for picture discs of Justin Bieber's Purpose or Disturbed's "The Sound of Silence" and people who camp out in front of Best Buy for Black Friday deals on HDTVs is the time of year. Then again, RSD has had a Black Friday version since 2011.

Many RSD early birds have had the displeasure of waiting in line behind an eBay reseller who buys up a store's entire stock of a special release—it's the kind of thing that can put a person off records, record stores, and even days. But the faithful keep coming back. This year's list of RSD releases is far from the best I've seen, but a handful of items have caught my eye—and among them are a few available for the first time, including previously unissued 1984 demos by grunge progenitors Green River and a seven-inch of unreleased songs, "Sweet Maria" b/w "Missouri Waltz (Missouri State Song)," by transcendentally inept cult band the Shaggs. Sun Ra's Spaceways (a compilation of live recordings from 1966 and '68) and Kevin Gates's recent Islah will be available for the first time on vinyl.

Most special releases are pressed in runs of 1,000 or more; anything made in smaller quantities is generally called a "regional release." One of the most enticing this year is native to Chicago: Cannots, a collaboration between jazz drummer Charles Rumback and guitar wunderkind Ryley Walker. The release I'm personally most excited about is regional too: Numero Group's cassette compilation of the complete recordings by early-90s Chicago rap group Stony Island. It's only available at the label's pop-up store at Comfort Station, where the surviving members of Stony Island will reunite for a performance at 2 PM.

Record Store Day's multitude of in-store performances give shoppers a good excuse to keep exploring even after the early-­bird deals evaporate. Chicago has more shops now than last year, and Pilsen is becoming a new hotspot for vinyl—Pinwheel Records and 606 Records have opened since 2015's RSD, and an online vintage and vinyl shop called Shady Rest is preparing to move into a storefront on 18th Street. To help you manage your options, the Reader has assembled an interactive map where each store's clickable "pin" includes details about in-stores, discounts, and other specials; because this information remains in flux, we'll continue updating it through Friday evening.

Your menu for this year's Record Store Day

Shops participating in Record Store Day usually stock a selection of special RSD releases, but in most cases retailers don't know till the last minute what they'll get. Consequently these listings don't mention RSD inventory—they're about special events, in-store performances, discounts, promotions, giveaways, and the like. Late changes are always possible, so it's a good idea to check with the store if you can.

We've omitted a few Chicago shops—Out of the Past Records, Let's Boogie Records & Tapes, and both locations of the Exchange—because they aren't doing anything for Record Store Day.
