When three out of four members left the band (including founding member Bartek Dobry), fans were rightfully worried what, if anything, would become of Weedpecker. Lucky for us the switch-up proved to be nothing less than a creative rebirth. What remained was a dreamy, truly mind-expanding take on ‘psychedelic’ music. But 2021’s IV: The Stream of Forgotten Thoughts took it far beyond the trademark heavy riffage to include both mellow jams and seething punk outbursts.
