Ahlgren has 2 Brit Floyd concerts.

Brit Floyd is a UK based Pink Floyd tribute band formed in 2010, whose stage presentation, comprising an elaborate light show, projections and inflatables, is loosely based on Pink Floyd's 1994 The Division Bell Tour, often referred to as the "Pulse" tour. The British Pink Floyd Show was born out of a split in The Australian Pink Floyd Show (TAPFS), with the name later shortened to Brit Floyd. Brit Floyd consists of musicians who have all performed with TAPFS.
