Need Info x residential workshop summer 2009 in GB

My son (15 years - and a good e-guitar player) is looking for a residential workshop (ca. 2 weeks - if possible Rockmusic) in Great Britain during the summer holidays - do you have any idea where I can find informations?
Thanks

Hi. For residential tuition I strongly recommend Guitar Weekends (website:www.guitarweekends.co.uk), based in Cumbia in UK. There are workshops covering a variety of styles: Blues, Rock, Country etc. (Guest tutors are brought in to teach). However, each course is no more than 3 days in duration, but the tuition is excellent, as is the homemade food, the hospitality, and the authentic country cottage accommodation!
