Buzzcocks helped shape British punk out of Manchester in 1976, fusing garage-rock scrappiness with fast, catchy melodies on records like Singles Going Steady. Founder Pete Shelley died in 2018; guitarist Steve Diggle took over vocals and still leads the band, whose recent album Attitude Adjustment lends this 50th-anniversary tour its name. They headline KYTTARO, a Radikal Events production. Opening are the STRESS, Athens punk veterans who formed in 1981 and play rarely: two original members return with three newcomers to run through their LP and the Athens Burning EPs.
