Former Dead Kennedys frontman Jello Biafra rose to prominence during the 1980s, but hasn’t mellowed a bit in the decades since. Appearing at Brick by Brick on April 27, he is touring with his new band, The Guantanamo School of Medicine. But fans of his previous combo will find the latest tunes cut from much the same cloth — punk rock with frantic splashes of spy and 1960s garage. The latest album, “Enhanced Methods of Questioning,” will please longtime Biafra listeners, but rest assured — he has also been known to include Dead Kennedys songs in the set as crowd pleasers. • Jello Biafra and The Guantanamo School of Medicine perform at 8 p.m. on Friday, April 27 at Brick by Brick, 1130 Buenos Ave. $12 in advance, $15 at the door. www.brickbybrick.com
