Leendert has 3 Good Charlotte concerts.

Good Charlotte is a pop-punk rock band often credited with helping to popularize the emo movement of the early 2000s. The band was formed in Waldorf, Maryland in 1996 by twin brothers Joel and Benji Madden. Both performed as vocalists while Joel acted as keyboardist and Benji as guitarist. Also in 1996, Paul Thomas joined as bassist with Billy Martin becoming rhythm guitarist in 1998. With Aaron Escolopio on drummers, Good Charlotte released its self-titled debut album in 1998. When he departed Chris Wilson joined for a short period, appearing on "The Young and the Hopeless" (2002) and "The Chronicles of Life and Death" (2004). Since his departure, Dean Butterworth has acted as a permanent drummer, appearing on "Good Morning Revival" (2007) and "Cardiology" (2010) before the band went on hiatus in 2011. After reuniting in 2015, Good Charlotte released two more albums: "Youth Authority" (2016) and "Generation Rx" (2018).
