Guitarist Gavin Harper has issued the following statement on the band's myspace page:
I'm very sad to report that Wilson has informed us last night that he is unable to continue in Alestorm due to a heavy touring schedule and a career that unfortunately leaves little room for time off.
The parting has been on excellent terms and there is no bad blood whatsoever, I, and all of Alestorm/Napalm Records wish Wilson the best of luck in his chosen path and we understand his decision completely.
We have got an excellent drummer filling Wilson's big shoes and has already proven himself as the perfect choice for the new Alestorm Drummer.
Details will be posted in the coming days after meetings have taken place with both band and record label on Monday in London.
I hope everyone joins me in our support both Wilson and our new drummer!
