Michael Kiske and Kai Hansen joined the current members for this tour for 2017, 2018 and 2019. Singing style During his earlier years Hansen's singing style was reminiscent of many thrash metal vocalists. Rather than using a smooth and clear style (like his successor Kiske) Hansen sang with a raspy sound, interluded by high-pitched screams for dramatic effect. Kiske was brought in as a singer, originally because Hansen had trouble singing and playing the guitar simultaneously, though later in his career he seems to have overcome these problems. Beginning from 1995 onward, Hansen has provided the vocals for his current band Gamma Ray. Around that time, Hansen's vocal style became more melodic and slightly clearer, more in the traditional power metal sense, while still retaining the slight nasal tone and rasp of his early years. Equipment For almost 20 years, Hansen has played ESP Guitars. He first started using them during his days with Helloween after hearing testimonials of ESP from artists such as George Lynch and Kirk Hammett of Metallica. Before Helloween, he had owned a white Ibanez guitar, and a Gibson Les Paul, then saved up for a Marshall amplifier by delivering newspapers. His main ESPs are red and pink ESP Custom guitars based on Jackson's Randy Rhoads model and two custom V models based on the classic Gibson Flying V shape. During the early 1990s, Hansen had used Stratocaster models. On his autobiography on the Gamma Ray website, he claims his first electric guitar was a white Ibanez Les Paul copy On the recent tour with Gamma Ray he has been seen using a Korina Epiphone flying V with EMG pickups. Hansen has used, and still uses, Engl amplifiers since the recording sessions of Keeper of the Seven Keys: Part II.
