I just checked the Record Store Day list last night, but it must have been a bit early. The Ten Club announced today, via their newsletter, that Mike McCready's Stooges tribute atop the Pike Place Market with Duff McKagan, Mark Arm, and Barrett Martin will be available this coming weekend, April 16th.
It's classified as an "RSD First" release, so presumably it may be available later, but quantities are super limited. Here are the details from the Record Store Day website.
Format: LP
Label: Monkeywrench
Quantity: 2500
Release type: 'RSD First' Release
On August 23rd 2015, Mike McCready (Pearl Jam), Duff McKagan (Guns n Roses), Mark Arm (Mudhoney), and Barrett Martin (Screaming Trees) performed a free live show on the rooftop of Pike Place Market in Seattle, WA to help benefit the new home of independent radio station KEXP. The group performed a tribute set to Iggy & the Stooges in front of a crowd of thousands that filled the streets outside of Seattle's world famous Pike Place Market. Proceeds from the sale of the vinyl record will benefit KEXP Radio.
