'Münchner Klaviersommer' was an annual concerts series that took place from 1981 to 1998 in Munich, Germany. Although the festival's name suggests a strong focus on piano music, it featured countless famous musicians from jazz and classical music - not just pianists. The concerts were usually held in July at The Gasteig, home of the Munich Philharmonic. In 1985, jazz quartet Phalanx appeared at the festival. The quartet featured guitarist James 'Blood' Ulmer, drummer Rashied Ali, tenor saxophonist George Adams, and bassist Sirone. This short-lived group, which was described as "an ad-hoc supergroup that thrived and disappeared", produced three albums in the period 1986-1988.
