Mother Focus is the fifth studio album by the band Focus, released in 1975 on Polydor (cat. no. 2310 408) in Europe, on Atco Records in North America and on EMI in Japan.[3] Some tracks on the album mark a departure from the progressive rock style that dominated the group's prior work, and herald a funk music style with light jazz and pop at the centre.[1] Bassist Bert Ruiter provided most of the themes, as van Leer had just recorded a solo album, O My Love, of his own music, and Jan Akkerman withheld compositions for Eli, his forthcoming album with .
The closing track, "Father Bach", is credited as a 'traditional tune', arranged and adopted by Thijs van Leer, but in reality it consists of the opening lines of J. S. Bach’s St. Matthew Passion.
