Ahlgren has 3 Bush concerts.

Bush was formed in London, England in early 1992. The band's debut album "Sixteen Stone" dropped in December 1994. Their second album "Razorblade Suitcase" followed in 1996 and reached number 1 on the Billboard Hot 200 chart in the US. In 2002, Bush broke up but reunited in 2010 with a new lineup. While they've been unable to attain the commercial success experienced in the late '90s, Bush is still widely acclaimed as a leader in the post-grunge and alt-rock scene.
