I am almost sure that the great musicians of Trio Penumbra are Waltel Blanco (guitar), Chiquinho (accordion) and Patané (violin)…
Sorry, I've made a mistake: the names I've post in the previous comment are from "Trio Surdina".For Trio Penumbra, based on the cover design, the harmonic seems to be played by Caçulinha.
Hi, Milan!Nice to meet you, here in your blog with all this new and wonderful music!Thank you and misterious Pedro from 300 discos for pack of J.R. Kelly albums. Great!!!What I'm find in Brazilian/Portugues part of Wikipedia:"Luiz Mainzi da Cunha Eça (!!!, before Tamba Trio) … Formou o trio Penumbra, tendo como componentes Candinho ao violão, e Jambeiro no contrabaixo, na rádio Mayrink Veiga". Is this the same thing or not?All the best from springtime Moscow!Bossanov
Yes, it seems there was possible two Trio Penumbra – one classical piano trio with Luisinho Eça as a leader, and other with guitar, accordion and violin… Caçulinha is among the authors – so he maybe a part of Trio?Bossanov
It's Bossanov again:In the begining of 1960th Caçulinha (acc) recorded some albums with Antônio Miranda (guitar) for label Chantecler! I suppose, they are part of Trio Penumbra for Musiplay. Who was violin player???
May be Lothar Gebhardt (vl) from Chantecler?Bossanov
