Racional, Vol. 1

Tim wrote every track. The recording date is disputed: Wikipedia says July and August 1974, Es Hoje a May 1974 start, Cliquemusic late 1974 for the backing tracks, and BBC Brasil February 1975. Distribution was minimal; Paulinho Guitarra said the musicians delivered records to shops themselves. The sleeve reproduces diagrams from the book Universo em Desencanto. Wikipedia describes a soul-reggae opener, a cappella interludes and a closing 12-minute funk-gospel track influenced by Stevie Wonder and Herbie Hancock.

AllMusic's Matt Rinaldi praised the lean arrangements blending funk and swing with blues, reggae, psychedelic rock and Motown-style soul, as Wikipedia paraphrases. Paulinho Guitarra said critics panned them at the time and that they became cult now. Trama reissued the CD in 2006, and the albums came to streaming services in 2018 or 2019 and again in a 2024 series. Collectors including Marcelo D2 are named in Es Hoje.
