Foetus is one of the major musical projects of NYC composer JG Thirlwell. Halt is the final Foetus album, and the first Foetus album in twelve years. It completes the cycle of an arc that began in 1981 with the first Foetus album Deaf. Thirlwell worked on Halt on and off over a period of eight years. As with each album he has made, he wanted to reinvent the music, use new forms, innovate and introduce new surprising forms into his musical palette, at the same time as feeling like a leap forward.

Halt deals with themes of war, religion, disease, media, global warming, anxiety, hypocrisy, conspiracy, death and mortality, among other things. Dread is a leitmotif through many of the Foetus albums and this one is no exception. Halt will be followed by its companion album, Leak, in 2027.
