Answer the question at the end by quoting:

D.O.A. is a Canadian punk rock band from Vancouver, British Columbia. They are often referred to as the "founders" of hardcore punk along with Black Flag, Bad Brains, Angry Samoans, the Germs, Negative Trend, and Middle Class. Their second album Hardcore '81 was thought by many to have been the first actual reference to the second wave of the American punk sound as hardcore. Singer/guitarist Joey "Shithead" Keithley is the only founding member to have stayed in the band throughout its entire history, with original bassist Randy Rampage returning to the band twice after his original departure.
1990's Murder featured rawer, almost thrash-metal production, rather than their original basic punk sound. The same year also produced a collaboration with Dead Kennedys singer Jello Biafra with Last Scream of the Missing Neighbors. In August 1990, Joey decided he was breaking up D.O.A. but, at the suggestion of promoter Dirk Dirksen, they did a farewell tour of the West Coast, playing their "final" show on December 1, 1990 at the Commodore in Vancouver. In 1991, they released a posthumous live album entitled Talk Minus Action = 0 while Keithley pursued an acting career.  19 months after D.O.A. broke up, Joey Shithead and Wimpy Roy had reunited as D.O.A in the summer of 1992. Fellow Canadian punk rock veteran John Wright from NoMeansNo suggested they hire Ken Jensen from Red Tide as the new drummer, which they did. The new lineup released an EP and two albums in the early 1990s, 13 Flavours Of Doom and Loggerheads. These albums found the band replacing the more hard-rock oriented sound of the 1980s with a return to punk rock, although it was a heavier, tighter brand of punk than their earlier work. These albums were produced by Wright, who also played keyboards on the recordings. The band then added Ford Pier on guitar and vocals.  Tragedy struck in 1995 when drummer Ken Jensen died in a house fire. The "Ken Jensen Memorial Single" EP was released on Alternative Tentacles, including two tracks each from D.O.A. and Red Tide. With John Wright filling in on drums, ninth full-length The Black Spot was recorded. The album featured a more basic, sing-along type punk rock sound that was reminiscent of the band's late 1970s and early 1980s output.  The late 1990s found the band's lineup in turmoil, with Wimpy Roy leaving the band after a decade and a half of service. Keithley experimented with different bassists and drummers and released the album Festival Of Atheists in 1998. By the early 2000s, the band had found a permanent drummer in the form of The Great Baldini. In 2002, Keithley put out his first solo album, Beat Trash, and original bassist Randy Rampage returned to the band after nearly 20 years for the Win The Battle album. However, the reunion did not last, with Rampage leaving the band again after the recording of the album, to be replaced by Dan Yaremko.  The Lost Tapes was the first release on Keithley's revived Sudden Death label, followed by Festival Of Atheists. During this period, Keithley also oversaw the re-release of the band's classic early records on Sudden Death, several of which had been out of print for many years.

Who played bass?

Randy Rampage

IN: Brown was born in Mineola, a small segregated town in east Texas marked by racial tensions, to Minnie Collins Boyd and Lewis Brown. Brown was the fourth of five children. During Brown's childhood, mob violence periodically erupted in Mineola, keeping African- Americans from voting. His first job was a shoeshine boy in a whites-only barber shop.

One of Brown's central campaign promises was his "100-Day Plan for Muni," in which he boasted he would fix the city's municipal bus system in that many days. Brown supported the "Peer Pressure" Bus Patrol program, which paid former gang members and troubled youth to patrol Muni buses. Brown claimed the program helped reduce crime. He fired Muni chief Phil Adams and replaced him with his chief of staff Emilio Cruz. In 1998, Brown was Mayor during the summer of the Muni meltdown as Muni implemented the new ATC system and Brown promised riders there would be better times ahead. A voter approved initiative in the following year would help improve Muni services. Brown increased Muni's budget by tens of millions of dollars over his tenure. Brown later said he made a mistake in over promising with his 100-Day Plan.  Brown helped mediate a settlement to the 1997 BART strike.  During his first term as mayor, Brown quietly favored the demolition and abolition of the Transbay Terminal to accommodate the redevelopment of the site for market-rate housing. Centrally located at First and Mission Streets near the Financial District and South Beach, the terminal originally served as the San Francisco terminus for the electric commuter trains of the East Bay Electric Lines, the Key System of streetcars and the Sacramento Northern railroads which ran on the lower deck of the San Francisco-Oakland Bay Bridge. Following the termination of streetcar service in 1958, the terminal has seen continuous service as a major bus facility for East Bay commuters; AC Transit buses transport riders from the terminal directly into neighborhoods throughout the inner East Bay. The terminal also serves passengers traveling to San Mateo County and the North Bay aboard SamTrans and Golden Gate Transit buses respectively, and to tourists arriving by bus motorcoach. Today, the terminal is being planned for redevelopment as a region wide mass transit hub maintaining the current bus services, but with a new tunnel that would extend the Caltrain commuter rail line from its current terminus at Fourth and Townsend Streets to the site. Once completed, Caltrain riders would no longer need to transfer to Muni in order to reach the downtown financial district. Additionally, the heavy rail portion of the terminal would be designed to accommodate the planned High Speed Rail lines to Los Angeles.  In 1998, The Berkeley, California-based Bicycle Civil Liberties Union, produced a two-hour documentary film in the muckraker journalism tradition, July 25: The Secret is Out, which gives evidence of Brown's designs for the Transbay Terminal site.
