Please answer the following question: Information:  - Andrew Giddings (born 10 July 1963) is an English keyboardist and was a member of Jethro Tull from 1991 to 2007.  - The Ian Campbell Folk Group were one of the most popular and respected folk groups of the British folk revival of the 1960s. The group made many appearances on radio, television, and at national and international venues and festivals. They performed a mixture of British traditional folk music and new material, including compositions by Campbell. Much of their popularity flowed from the variety of their performance which included a mixture of solos, group vocals and instrumentals.  - A record label or record company is a brand or trademark associated with the marketing of music recordings and music videos. Often, a record label is also a publishing company that manages such brands and trademarks, coordinates the production, manufacture, distribution, marketing, promotion, and enforcement of copyright for sound recordings and music videos; conducts talent scouting and development of new artists ("artists and repertoire" or "A&R"); and maintains contracts with recording artists and their managers. The term "record label" derives from the circular label in the center of a vinyl record which prominently displays the manufacturer's name, along with other information.  - Chrysalis Records is a British record label that was created in 1969. The name was both a reference to the pupal stage of a butterfly and a combination of its founders' names, Chris Wright and Terry Ellis. It started as the Ellis-Wright Agency.  - Fairport Convention are an English folk rock and electric folk band. Formed in 1967, they are widely regarded as a key group in the English folk rock movement.  - Electric folk is the name given to the form of folk rock pioneered in England from the late 1960s, and most significant in the 1970s, which then was taken up and developed in the surrounding Celtic cultures of Brittany, Ireland, Scotland, Wales and the Isle of Man, to produce Celtic rock and its derivatives. It has also been influential in those parts of the world with close cultural connections to Britain and gave rise to the genre of folk punk. By the 1980s the genre was in steep decline in popularity, but has survived and revived in significance, partly merging with the rock music and folk music cultures from which it originated. Although in Britain the term folk rock is often used synonymously with electric folk, commentators have returned to this term as a means of distinguishing this as a clear and distinct category within the wider folk rock genre.  - A keyboardist is a musician who plays keyboard instruments. Until the early 1960s musicians who played keyboards were generally classified as either pianists or organists. Since the mid-1960s, a plethora of new musical instruments with keyboards have come into common usage, requiring a more general term for a person who plays them. These keyboards include:  - Catfish Rising is the 18th studio album by the British rock group Jethro Tull, released in 1991. It is the first Tull album to feature keyboardist Andrew Giddings.  - Roots to Branches is the 19th studio album by the British band Jethro Tull released in September 1995 . It carries characteristics of Tull 's classic 1970s art - rock and folk - rock roots alongside jazz and Arabic and Far Eastern influences . All songs were written by Ian Anderson and recorded at his home studio . This is the last Tull album to feature Dave Pegg on the bass , and the first to feature keyboardist Andrew Giddings as an official band member , although he had contributed to Catfish Rising ( 1991 ) on a sessional basis . It was also the final Tull album to be released through long - time label Chrysalis Records . In January 2007 , a remastered edition of the album was released . It contained no bonus tracks .  - Dave Pegg (born 2 November 1947) is an English multi-instrumentalist and record producer, arguably most visible as a bass guitarist. He is the longest-serving member of the pre-eminent electric folk band Fairport Convention and has been bassist with a number of important folk and rock groups including The Ian Campbell Folk Group and Jethro Tull.
