Lead Upturn 2009: Summer Day & Night Fever

Lead Upturn 2009 ~Summer day & Night Fever~ is the sixth concert DVD released by the Japanese hip-hop group Lead, released a year after their previous concert DVD on December 9, 2009. It charted at #41 on the Oricon charts, remaining on the charts for one week.

While the tour did not have a corresponding album, the songs chosen were ones that were best suited for summer days and nights, with the first half of the concert being compiled of upbeat pop songs and the second half composed to their more dance-styled songs.
