HSAS-Through the Fire was a one shot deal that happenned while Neal Schon was on break from Journey in 1983. They played 2 or 3 shows in the Bay Area and the album was taken directly from those live recordings.
I love this album. Schon plays better here than on any Journey album in my opinion, and it's definitely Sammy's best work outside of Van Hagar. Find this album if you can, it's well worth it!
