(#5); "Reason" (#8); "Try" (#15); and their biggest hit single, "Castles in the Sky", which reached #3 and spent seven weeks in the top 10 in the summer of 2001. This last song also reached the Billboard Hot 100 chart in the U.S., where it peaked at #91. The album itself peaked at #7 in the UK, where it achieved Gold status after only four weeks. The album title was inspired by taking the first letters of the names of each member of the act; Annemie, Christophe and Eric.
