As 
Soft Machine moved further away from rock on 
Third and Fourth, drummer/vocalist 
Robert Wyatt's dissatisfaction with the band's direction grew and, by the time sessions started for 
Fifth in late 1971, he had left permanently to form 
Matching Mole. While the instrumental Fourth had forayed deep into jazz-rock territory, 
Fifth found 
Soft Machine working almost completely in the jazz idiom. At the time of 
Wyatt's departure, keyboardist 
Mike Ratledge commented that the band's co-founder had "never enjoyed or accepted working in complex time signatures." However, 
Wyatt's replacement -- 
Phil Howard -- didn't prove to be the kind of timekeeper 
Ratledge and bassist 
Hugh Hopper had in mind, and his free jazz orientation led to his dismissal during the recording of the album. 
Howard's propulsive rhythms nevertheless make a vital contribution to memorable 
Ratledge compositions like "All White" and "Drop" as they gather momentum and coalesce into driving grooves. "All White" is focused largely on 
Elton Dean's sax performance, while "Drop" ultimately showcases the intense busy fuzz of 
Ratledge's organ. In places on 
Fifth, there does seem to be an element of tension between the more structured approach of 
Ratledge and 
Hopper and the free-form inclinations of 
Dean. The looser style of 
Dean's squalling sax playing is foregrounded particularly on "As If" -- another 
Ratledge piece. A certain constituency among 
Soft Machine fans tends to concentrate on the band's earlier releases and to consider everything from Fourth onward less compelling. That attitude has something to do with not being especially interested in jazz, so it's not entirely fair to dismiss this album without qualifying such a judgment. Anyone expecting to hear a rock album or a jazz-rock album will probably be disappointed with 
Fifth. This is essentially a jazz record, more concerned with texture and interplay than with song-based structures. [The 2007 remastered edition features a previously unreleased version of "All White" as a bonus track.] ~ Wilson Neate
