The third Spiegel, or mirror, takes the Portuguese acoustic octet led by violist Ernesto Rodrigue through an extended improvisation and its reflection, captured live at the 2021 CSFest XV, at O'Culto da Ajuda, by performing and recording their performance in a first pass, and then playing over the first improvisation, layering and extending their work.

Far from the reductionist/minimal improvisation often associated with the Creative Sources label and the work of both violist Ernesto Rodrigues and cellist Guilherme Rodrigues, this quartet session with double bassist Joao Madeira and Jose Oliveira is a highly charged and energetic affair, improvising through a suite of eight tightly controlled conversations of "Chaos".

Performing live at SMUP, in Parede, Portugal in 2022, the bass-oriented chamber quintet of Ernesto Rodrigues on viola, Bruno Parrinha on bass clarinet, Joao Madeira on double bass, Hernani Faustino on double bass and Jose Oliveira on percussion balance jazz and contemporary compositional approaches to their sophisticated and extremely detailed improvisations.

The sixth release by Creative Sources' detailed electroacoustic improvising group Suspensão led by violist Ernesto Rodrigues, with Guilherme Rodrigues on cello, Nuno Torres on alto sax, Antonio Chaparreiro on electric guitar, Carlos Santos on computer and Jose Oliveira on percussion & inside piano, is this impressive performance at "Temporada Miso Music 2009" in Lisbon.

Aptly described as chiaroscuro--a veritable play of light and shadow in quick-witted--through nearly microscopic and highly interactive acoustic improvisation from the quartet of Ernesto Rodrigues on viola, Maria da Rocha on violin, Bruno Parrinha on clarinet & bass clarinet and Jose Oliveira on percussion, performing live at Galeria Monumental, in Lisbon in 2022.

Two strings, sax, bass and percussion from the free improvising chamber jazz quintet of Mia Dyberg on alto saxophone, Ernesto Rodrigues on viola, Guilherme Rodrigues on cello, Johan Moir on double bass and Jose Oliveira on percussion, in an interactive and dynamic live performance recorded in 2018 during the CreativeFest XII at O'Culto da Ajuda, in Lisbon, Portugal.

The Portuguese large improvising ensemble String Theory is heard live during the CreativeFest#12, at O'Culto da Ajuda, in Lisbon, Portugal in 2018, in an extended improvisation of incredible layering and restraint, making an amalgam of mostly acoustic string sources sound electronic and hallucinatory, an incredible achievement in string sonics.

One of Portugal's most interesting large scale lowercase ensembles led by violist Ernesto Rodrigues, with frequent Creative Sources collaborators including Nuno Torres on alto sax, Carlos Santos on electronics, Guilherme Rodrigues on cello, Miguel Mira on bass, 14 musicians move with subtlety in a tapestry of electroacoustic resonance and mystique.

Referencing the work of French artist and composer Yves Klein, this large group of Creative Sources regulars perform the 4 part Monochrome Bleu Sans Titre, a subtle and rich work of acoustic and electronic improvisation.
