Headquarters is the third album issued by the Monkees and the first with substantial songwriting and instrumental performances by members of the group itself, rather than by session musicians and professional songwriters. After a struggle for creative autonomy with their record label, the group had been allowed to record by themselves. Headquarters reached No. 1 on the Billboard 200 chart and was certified double platinum in the United States with sales of more than two million copies within the first two months of release. It peaked at #2 on the UK charts. It is included in the 2006 book 1001 Albums You Must Hear Before You Die.
