FEATURED ALBUM:

Radio Spectrum Secrets 

by 

In Vitro

Released 2025 on Silent Flow

Free download available on:

4 tracks. 24 mins

There is doubtless a whole history of comparing music with cooking, but it is not because I am writing this at my kitchen table that I raise it in my first sentence. In searching inside myself for the way to introduce Radio Spectrum Secrets by Mexico’s In Vitro and do justice to the sheer pleasure I have in listening to it, what came to me was that way a very good cook, with very good ingredients and a divine sense of timing need only do a few, albeit crucial, things and then just lets the magic be. For me, this is Radio Spectrum Secrets: perfectly cooked and presented.

Really an E.P. at 24 minutes, it certainly whets the appetite for more from the artist behind the In Vitro sounds, Quetzal Contla, and plenty can be found at his tumblr and Bandcamp sites (links below) to fulfil that urge.

Perhaps it is because my own music journey began in the 1980s with a Roland SH-101’s built in monophonic steptime sequencer that I have such an enduring love of the lonely sequence or transposed arpeggio line holding the foreground. This also taught me how some lines repeat and move with a grace that is as repeatable as it is hypnotic, where  others last only two repeats before you are tired of them. In the opening track, Personas En Exhibición, not only do we have a wonderful example of the former but also field recording working as both a context and a foil to the music and hence becoming the music. As human voices join the ambience, both elements share the foreground playfully before a gentle and simple ending concludes the track.

Next, the title track establishes a very different but equally evocative and expectant atmosphere, again with the simplest ingredients: a single wavering note and a delightfully phasing and filtered radio voice and interference. Into this a few extraneous analogue noises are worked, the radio tuning shifted just a tiny amount to create a profound and darkening climax.

What sounds at first like car alarms at the start of the shortest of the four, Jardins A La Nit (Occitan language) give way to a meandering, jazz trumpet performqnce by horiso. Amongst the palette of sounds this is a beautifully refreshing intermezzo both in its intricate details and also in the way it prepares you for the final ‘course’, Children of God.

As dessert, a lightly voiced didgeridoo drone is suddenly commanded by a supremely confident and trip-hoppy rhythm loop. Echoey voice samples and various additional tonal and percussive sounds skitter comfortably on top until the track dies out into slowly receding static hiss. 

This is a surprising and satisfying meal that delights with its moods and simplicity. It also belies an impressive creative touch that well knows the innately beautiful qualities of its elements and does not crush or overcook them.

Be with this.

In Vitro is Mexican musician, radio producer & DJ Quetzal Contla who has since 2004 released original music, mixes and remixes on several labels and netlabels around the world, often incorporating different styles of music in one project. He is also creative director of Breathe Compilations (2008-2018).
