Marc Friedli AKA Skymark is a producer, vinyl collector, DJ and keys player who likes to connect with his audience on a deeper level. He’s been collecting the finest private press as well as classic records of Soul, Gospel, Disco, Jazz and Brazilian music since 1995 with true love and devotion, in search of these records that bring the wet and red eyes. Since 2007, he has released a string of albums and EPs on his own label as well as on imprints like Neroli, Mukatsuku Records, or Rush Hour, showing his impressive electric piano keyboard skills and unique style with an array of vintage synthesizers like ARP, Prophet, Moog, Roland, or Korg. On his privately pressed and strictly limited album, Primeiras Impressões, he delivered nine, gently jazzy tunes that process his experiences in the heat of Rio De Janeiro. They are intensely spiritual, they avoid ornamentation, and they bow before jazz history with a gentle respect, while adding an elegantly explorative and thrillingly uplifting freshness to the genre with deep discreet minimal funk and light-as-a-feather piano-melodies, as if the keyboard were a saxophone.
