The Matrix was Marty Balin's idea. And a clever idea it was. He converted a pizzeria into a club and used his band, the Jefferson Airplane, as the house band.
One of the other bands that played there at the start of the Matrix was the Great Society. Fans of Grace Slick will immediately recognize the name of the band she left to join Balin and the Airplane. Her she is with the Great Society at the Matrix in 1966 singing a song that would also become a staple of the Airplane:
San Francisco Sound
The Matrix became the early hub of what would become the San Francisco Sound, but the venue featured bands from all over during it's relatively brief life until 1972. Dozens of unknown upcoming bands played there including:
The club re-opened at 412 Broadway, but closed in fall of 1973. Later new renters remodeled the space the first Matrix occupied and turned it into a nightclub with only a DJ, and no live music. Today the space is called the Matrix/Fillmore, evoking the glory days of the San Francisco sound, though there is no live music. According to the Matrix/Fillmore site the venue is "one of San Francisco's most intimate, boutique-style music venues where you can enjoy handcrafted cocktails, bottle service and premium champagnes while dancing to a range of dance music, from House to 70s, 80s, 90s genre. Located in San Francisco's Marina district, MatrixFillmore is also a stylish venue for private corporate and social events."
Scott Powell was born in Dallas, Texas, on August 13, 1948. Yes I know. Scott Powell is not a household name. Unless, of course, you are in his house. Sha Na Na was not a household name at the Woodstock Music and Art Fair either, but that Sunday morning they came out and performed for the many thousands of fans who had stuck it out and awaited Hendrix. From his site: " He performed with the group at the Woodstock Festival, Fillmore East and West, in Europe and Japan, on the syndicated television series, Sha Na Na, and in the movies."
1970 – Woodstock – as himself with Sha Na Na
1972 – Dynamite Chicken – as himself with Sha Na Na
1978 – Grease – with Sha Na Na as Johnny Casino and The Gamblers
1980 – Caddyshack – Gatsby
1994 – Woodstock Diary – as himself with Sha Na Na
2003 – Festival Express – as himself with Sha Na Na
He left the band in 1980 and returned to Columbia to pursue a career in medicine. To say that that's not where many of the Woodstock performers went is an understatement, of course.
