London A Cappella Festival

However you spell it, a cappella is huge right now. This festival which is now in its seventh year explores the potential of the unaccompanied human voice through genre-spanning concerts, workshops, talks and interactive events. Highlights include American country singers Home Free, and BBC2 Naked Choir's Dominic Peckham and Mark De-Lisser who'll be running a workshop for enthusiastic singers of all ages and abilities. See the London A Cappella Festival website for the full schedule.
