Question: Where was the rock bank with which Jorma Kaukonen was best know for his work based? 
Context: Too Many Years is a Jorma Kaukonen studio album released in August, 1998.  It was his last studio album on Relix Records.  Michael Falzarano returned to play guitar and help produce (as he did on the previous Kaukonen solo album).  He also sang lead on several tracks.  The keyboard work was now handled by former Jefferson Starship keyboardist Pete Sears, who had been playing with Hot Tuna since 1992.  After this album, the three began to perform as the "Jorma Kaukonen Trio" and recorded a live album for Relix, "Jorma Kaukonen Trio Live". Jorma is the second solo album by Jorma Kaukonen of Hot Tuna and Jefferson Airplane.  Hot Tuna had stopped touring in 1977 and Jack Casady had moved on to the band SVT.  Bill Thompson and the staff that had managed Hot Tuna and still managed Jefferson Starship in 1979 continued to manage Kaukonen.  David Kahne was hired to produce and the new solo album was released on RCA.  The album consists entirely of Jorma's own vocals and his own electric and acoustic guitar work with many original songs written by Kaukonen.  The last track is a poem recited by Kaukonen with no instrumental backing. Magic is a live Jorma Kaukonen album containing performances of acoustic songs from Jefferson Airplane and Hot Tuna albums recorded during his solo tour of 1984.  After a brief reunion tour in 1983 with Hot Tuna, Jorma had continued to play solo and eventually landed a contract with Relix Records.  In addition to releasing Kaukonen's new solo recordings, Relix also released live Hot Tuna recordings from the 1970s, with the albums "Splashdown" and "Historic Live Tuna".  In 1995, Michael Falzarano remastered the album and produced a new version that Relix released as the CD "Magic Two". Jefferson Airplane was a rock band based in San Francisco, California, who pioneered psychedelic rock.  Formed in 1965, the group defined the San Francisco Sound and was the first from the Bay Area to achieve international commercial success.  They were headliners at the three most famous American rock festivals of the 1960s—Monterey (1967), Woodstock (1969) and Altamont (1969)—and the first Isle of Wight Festival (1968) in England.  Their 1967 break-out album "Surrealistic Pillow" ranks on the short list of the most significant recordings of the "Summer of Love".  Two songs from that album, "Somebody to Love" and "White Rabbit", are among "Rolling Stone's" "500 Greatest Songs of All Time." Blue Country Heart is a Jorma Kaukonen studio album released in June, 2002.  It was his first album on a major label since 1980's "Barbeque King".  Kaukonen didn't write any new compositions for the album, and instead played mostly country-blues cover songs.  Kaukonen again relied on the talents of other musicians for this solo effort, but turned to musicians he had not previously worked with on any project.  Sam Bush, Jerry Douglas, Byron House and Bela Fleck helped add more of the country flavor not present in previous Kaukonen solo efforts.  The album was nominated for a Grammy award in 2003 for "Best Traditional Folk Album." Jorma Kaukonen Trio Live is a live album taken from performances from Jorma Kaukonen's 1999 solo tour, and his last album for Relix Records.  Performing with Kaukonen were Michael Falzarano and Pete Sears who had both been present on his previous solo album, "Too Many Years", and had performed with Hot Tuna on their last release, "And Furthurmore...".  After release of this album, Kaukonen and Jack Casady began to perform as "Jack & Jorma, The Original Acoustic Hot Tuna" and Falzarano and Sears performed much less with Hot Tuna and Kaukonen's solo act, with Sears finally leaving in 2001 and Falzarano leaving in 2002. Quah is the first solo album by Jorma Kaukonen of Hot Tuna and Jefferson Airplane.  The album was recorded with Tom Hobson.  The initial plan was to have side-A be Kaukonen and side-B be Hobson.  However, RCA felt that Hobson's recordings would not be accepted by the public.  Initially the record was planned to be released in mid-1973, but because of the issues with Hobson, Kaukonen returned to the studio to record new tracks for side B in May 1974.  Only "Blue Prelude" and "Sweet Hawaiian Sunshine" of the original 1974 release feature Hobson's lead vocal, although he also plays guitar on "I'll Let You Know Before I Leave."  On the CD reissue, Hobson is featured on all bonus tracks except for "Lord Have Mercy." Jorma Ludwik Kaukonen, Jr. ( ; ; born December 23, 1940) is an American blues, folk, and rock guitarist, best known for his work with Jefferson Airplane and Hot Tuna. " Rolling Stone" magazine ranked him #54 on its list of 100 Greatest Guitarists. Christmas is a Jorma Kaukonen studio album released in July 1996.  It was the only themed album Kaukonen recorded and was a departure from the usual Rev. Gary Davis influenced tunes.  It included new Christmas-themed compositions as well old hymns such as "Silent Night."  Like the previous album, "The Land of Heroes", "Christmas" incorporated the work of Michael Falzarano and Fred Bogert.  Kaukonen's wife Vanessa also performed vocals and co-wrote one song.  It was also the only time Kaukonen performed keyboards on an album. Final Vinyl is a Hot Tuna compilation album.  At the time the album was assembled, Jorma Kaukonen and Jack Casady had stopped performing together and were on to newer endeavours.  Kaukonen recorded a solo album, "Jorma", and Casady joined the band SVT.  Kaukonen signed to RCA Records and Casady moved to 415 Records.  This marked the end of Hot Tuna on the Jefferson Airplane owned Grunt Records, so a "final" compilation album was assembled.  Kaukonen and Casady reunited to perform as Hot Tuna in 1983 and moved to the Relix Records label, where they released material until the late 1990s.
