If I have understood the back cover text correctly, this should be Moacyr Marques' first recording.
The back cover of this unlisted rarity credits the whole formation of musicians participating:
Moacyr Marques - Sax-Tenôr
Zequinha Marinho - Piano
GabrieL - Basso
Wilson - Batteria
Pernambuco do Pandeiro e Pedro dos Santos - Ritmo
Also the 4 tracks (not included in any of his albums, as far as I know):
1. Menina Moça (Luiz Antonio)
2. Alguém Me Disse (Jair Armorim / Evaldo Gouvêia)
3. Me Leva (José Garcia / Anisio Silva / Silas de Oliveira)
4. Idéias Erradas (Dolores Duran / Ribamar)
MOACYR'S FIRST RECORDING
Créditos: Pedro & 300discos
GUESS by Bossanov:
I think, Wilson is Wilson Das Neves, taking part at Jazz & Bossa-Nova on Tiger. May be Gabriel be Gabriel Bezerra de Mello?
DATE OF RECORDING APPROXIMATION by Frank-Oliver:
It seems this EP came before the Tiger LP, so the date is 1959 / 1960.
UPDATED EXPIRED LINKS by Milan Filipović:
I have updated the links in another reality to those albums by Moacyr Marques that could be re-uploaded.
