Led Zeppelin
Pink Floyd
Metallica
Eagles
Honorable mentions are too numerous to list them all, and my leanings have varied over the years and/or depending on mood, but have included bands like AC/DC, Alice in Chains, Jane's Addiction, Jethro Tull, early U2, and plenty of flashes in the pan ranging anywhere from prog rock to psychedelia to industrial to heavy metal to reggae to folk (if I'm feeling really nostalgic and mellow)
