David Cross, a former violinist of the revered progressive-rock band King Crimson, will be in Athens for two shows this week, on Friday and Saturday, at the Small Music Theater in the Koukaki district (33 Veikou, tel 210.924.5644). His visit will include a workshop open to musicians of all levels and styles at the same venue hours ahead of Saturday’s show. For his Athens appearances, Cross will be backed by veteran Greek prog-rock band the Explorers, whose members have also worked with acts such as Vangelis and Socrates. Though best known for his output with King Crimson in the early to mid-1970s, Cross has remained active in a variety of artistic disciplines. Toward the end of his tenure with King Crimson, whose ranks included the musical wizard Robert Fripp, Cross formed the improvisational rock group Ascend and also began his long association with theater. In the 1980s, Cross occupied himself with audiovisual and video projects, while also performing in jazz outfits, recording solo projects and doing session work. He has released several solo albums, including 1998’s «Exiles,» a project that was more song-oriented than previous efforts, which featured guest appearances from Fripp, Peter Hammill and others. In the late 1990s, Cross formed the label Noisy Records and released «Civilizations,» an album by his improvised-fusion project Radius. In more recent times, he has collaborated for interdisciplinary performances with dancer Verity Blackman and painter Maurizio Pio Rochhi.
