My tip: Just look on YouTube recordings of concerts and head off into the concert halls. The CD is a 5 star worthy - the concerts least 6 star, if not more ... :-)
I look forward to the concert in the Batschkapp in a few days. In September in Hanau we went with the kids with us.
Conclusion: Great CD but, the concerts are even better. Therefore, only buy the CD, learn lyrics and then off to the concert and to join in the singing! :-)
