Leslie Howard gave a series of ten Liszt recitals in London's Wigmore Hall. By excluding Liszt's arrangements (fantasies and transcriptions) of other composers' works, and by selecting only the final versions of Liszt's original works for solo piano, Howard was able to represent Liszt's entire solo piano oeuvre in ten mammoth recital programmes. The founder and Managing Director of Hyperion Records was present at these recitals, and invited Howard to record for the label. All Liszt's versions of his piano music were included, including more than 300 premiere performances and recordings, and pieces unheard since Liszt's lifetime, and also all Liszt's arrangements of other composers' works. Four discs were given to Liszt's seventeen works for piano and orchestra, about half of which were premiere recordings made from unpublished manuscripts. The series ran at first to 94 full-length CDs, and earned Howard a place in The Guinness Book of Records for completion of the largest recording project ever undertaken by a solo recording artist (including pop artists). (The second volume of works for piano and orchestra included a bonus disc, not counted in the series numbering, which contained Ungarische Zigeunerweisen, a work for piano and orchestra by Liszt's favourite female student Sophie Menter: Liszt's exact involvement in the work is unknown, but he probably helped Menter in the composition of the solo part in the year before his death; the work was orchestrated seven years later by Menter's friend Pyotr Ilyich Tchaikovsky, who conducted Menter in the premiere the following year). The last disc of the Liszt series was recorded in December 1998, and released on 22 October 1999, Liszt's birthday. Since completion of the project, three supplementary volumes have been released (the third of which is a double CD) as further Liszt manuscripts have come to light. The total number of CDs in the series is now therefore 99. A boxed set containing all 99 discs has been issued by Hyperion Records in 2011 in honor of the 200th anniversary of the birth of Liszt. In 2018, a new disc was released, including some inedit works, like the first version of the Hungarian Rhapsody No. 1, and the Kavallerie-Geschwindmarsch, which was believed lost for over a century. Claims by other pianists to have recorded the complete piano works of Liszt are demonstrably incorrect. Such claims include those by France Clidat, whose Liszt recordings total just 28 CDs; and Gunnar Johansen,
