A Liquid Tension reunion would be a dream come true for me. I just recently listened to some LTE last week as I was re-ripping music to my laptop/portable HDD, and I forgot just how GOOD these songs were! Even the improv is so entertaining, and I'll definitely say that Tony Levin's influence is definitely felt in the band as well. It won't be a DT re-hash with JR/JP/MP, and I think if they get back together, there will be the same LTE chemistry that they had in the last 90s, and again in 2008 on their 10th Anniversary tour.
I think if they get together to do another album in the next year or two, and release the album in 2022, they could do a 25th Anniversary Tour in 2023, and I'm sure it'll be a HUGE hit.
