Tomorrow evening, the Ma'abada venue in Jerusalem will host one of the biggest names in contemporary classical music and modern jazz, German trumpeter and composer Markus Stockhasen, alongside Dutch-born clarinetist Tara Bouman. 50-year-old Stockhausen, son of acclaimed contemporary composer Karlheinz Stockhausen, started his performing career at the age of four, when he appeared as "child at play" in his father's theatrical work, Originals. He took his first piano lessons at six, taking up the trumpet six years later. His performing career began in earnest in 1974, as a member of the Key group that aappeared at the Newcomer Jazz Festival in Frankfurt, and he followed that up with a part in his father's opera Sirius at the Washington Bicentennial. In fact, the trumpet part in Sirius was written especially for the younger Stockhausen, and father and son have collaborated many times over the past three decades. The familial musical context has stretched even further over the years, with Markus' multi-instrumentalist younger sibling Simon joining him on many recordings and shows across the globe. The brothers have written several film and theater scores together, and they created two open-air spectacles for the fifth and 10th anniversaries of the Philharmonic Hall in Cologne, which attracted audiences of 70,000 and 100,000 respectively. The trumpeter's recent works include Choral and Sehnsucht for jazz trio and orchestra, as well as works commissioned and performed by the London Sinfonietta and noted Swiss orchestra Musikkollegium Winterthur. This week's confluence with Bouman offers a rare occasion to catch two of the leading luminaries on the global contemporary music scene in highly exploratory action. Saturday night's performance is scheduled for 9:30. For more information, visit www.maabada.org.il.
