Jan Milosz Lisiecki (born March 23, 1995) is a classical pianist. He is most well known as being extremely accomplished in piano as well as in academics at a young age.

“I concisely remember the moment when my hands and feet gradually gained control and I was able to make the piano sing. My powerful relationship with the piano began and I started to discover my voice. As I play, I feel that the magic of the music is emerging from the piano, and also is developing in me – I feel the light shining into my heart. I experience joy, happiness, love; but also sadness and pain. And I have the strong desire to share it with others.” – Jan Lisiecki

Jan Miłosz Lisiecki was born in Calgary, Canada to Polish parents. He has been studying piano since the age of five at the Mount Royal University Conservatory.

Andrew Jackson (March 15, 1767 – June 8, 1845) was the seventh President of the United States (1829–1837). Based in frontier Tennessee, Jackson was a politician and army general who defeated the Creek Indians at the Battle of Horseshoe Bend (1814), and the British at the Battle of New Orleans (1815). A polarizing figure who dominated the Second Party System in the 1820s and 1830s, as president he destroyed the national bank and relocated most Indian tribes from the Southeast to west of the Mississippi River. His enthusiastic followers created the modern Democratic Party. The 1830–1850 period later became known as the era of Jacksonian democracy.

Jackson was nicknamed "Old Hickory" because of his toughness and aggressive personality; he fought in duels, some fatal to his opponents. He was a rich slaveholder, who appealed to the common men of the United States, and fought politically against what he denounced as a closed, undemocratic aristocracy. He expanded the spoils system during his presidency to strengthen his political base.

John Doan (Born May 16, 1951) is one of the best-known harp guitarists in the world. In addition, he is a performer, Emmy-nominated composer, historian, instrument collector, and university professor.

Doan grew up in Venice, California, and at the age of eleven began playing the guitar, first a 12-string, and later a double-neck electric in a rock band. Later, while studying music at California State University, Northridge he was introduced to classical guitar. He really enjoyed the music for the lute and was amazed at the sound of its many strings. Later when he found a century old harp-guitar on the back wall of a music store, it called to him with its beautiful shape and unusual collection of extra strings. He relates: "I was achingly curious and wanted to transform its silence and neglect into something alive and vibrant. It was and continues to be an adventure to play music on the harp-guitar." After moving to Oregon, Doan earned his master's in musical education from Western Oregon University and served on the faculty there. He studied the renaissance and baroque lute in the Netherlands. Doan's music has a strong classical influence and he also finds inspiration in folk traditions, Irish musical traditions in particular. He is an associate professor of music at Willamette University in Salem, Oregon, a historian, and a multi-instrumentalist specializing in unusual vintage instruments. Over the years Doan has played with many folk and country artists, including Donovan, Burl Ives, Larry Carlton, and Chet Atkins.

Josep Ferran Sorts i Muntades (baptized 14 February 1778 – died 10 July 1839) was a Spanish classical guitarist and composer. While he is best known for his guitar compositions, he also composed music for a wide range of genres, including opera, orchestra, string quartet, piano, voice, and ballet. His ballet score Cendrillon (Cinderella) received over one hundred performances. Sor’s works for guitar range from pieces for beginning players to advanced players such as Variations on a Theme of Mozart.

Sor gave concerts throughout Europe, including in England, Paris, Berlin, and Warsaw. Before the early 19th century, the guitar was little-known in England. Sor seems to have created a market for himself there and then met the demand. Sor’s contemporaries considered him to be the best guitarist in the world, and his works for guitar have been widely played and reprinted since his death.

As Sor's works were published in various countries, his name was translated, leading to variations in the spelling. Variations have included Joseph Fernando Macari Sors, Fernando Sor, Ferran Sor, Ferdinand Sor, and Ferdinando Sor.
