Amnesia long-time resident CAAL comes back to Roush with his studio mate Baum. The spaniard combo has been a regular name on tech-house top labels such as elrow, Sola or Repopulate Mars, where they have signed a great bunch of bangers. Some of this tracks have been remixed by reputed producers as Nathan Barato, Eskuche or Eli Brown giving the duo an international exposure. Regarding to his debut EP on Roush, title cut 'Back & Forth' opens with an actual and arpeggiated bassline which infuses the track a fast vibe. A female woman repeating an hypnotic phrase is used in order to captivate listener. The voice has a clever sci-fi treatment that gives a robotic shape. 'Makin' Moves' is another fantastic cut with a firm bet on the always popular and effective 303-acid-sound that closes the EP in a raver-style.
