This first EP from London tech/house duo Marsha demonstrates a real understanding of what the underground scene wants. The bombastic and colourful arrangements have a tried and tested dance floor impact. Heavy bass lines, strong percussive grooves and good hooks culminate for a strong handed opener. Highlights include the glitch vocal led 'Gumball' and the swaggering bass line of the title track 'Penelope.''Don't Wait Up' shows a more sensitive side with an original vocal provided by Alex.
