Hagar Schon Aaronson Shrieve (also known as HSAS) were a band featuring lead vocalist Sammy Hagar, lead guitarist Neal Schon, bassist Kenny Aaronson and drummer Michael Shrieve. The story goes that they rehearsed less than a month Warfield in San Francisco, it's called Through the Fire.

The album includes a cover of Procol Harum's "A Whiter Shade of Pale". Sammy Hagar and Neal Schon always said they did that as a one time album. It happened right around the time that Schon was done with Journey's "Frontiers" album.

They started originally with drummer Denny Carmassi, but Denny left to play for Heart. They picked up Kenny Aaronson and Michael Schrieve (whom Schon had played with in Santana). They played live for 3 days, MTV played the live concert they gave and they took the recordings, cut 5 songs off the set, edited out the crowd and released as originally done with no overdubs.

Schon and Hagar reunited to do a project called PlanetUs.

Now they are back together to form a new band and go a different way with Michael Anthony (former Van Halen now Chickenfoot Bassist) and Chad Smith (Red Hot Chilli Peppers and Chickenfoot) and Sammy claims everyone he plays with now will have a last name to keep the HSAS band going.
