Roel Meelkop, - composer of modern music, which he performs on his laptop. He's also a member of Zebra, Goem and Kapotte Muziek with Frans de Waard and Peter Duimelinks and a member of THU20. A serious old man but with a long history in music. Before THU20 he was a member of Club Rialto, a bass, vocals, rhythm box (with various future members of THU20) band and Meelkop had his solo project called Happy Halloween (before using the monikker Mailcop and releasing two excellent tapes on Midas Music). As Happy Halloween he played his own brand of popmusic, experimental and industrial music using guitar, rhythmbox and a bit of electronics, but which sounds remarkably fresh in these days.
